Available in PDF, EPUB and Kindle. Book excerpt: Thanks to its compatibility with the current CMOS technology and its potential of seamless integration with electronics, silicon photonics has been attracting an ever-increasing interest in recent years from both the academia and industry. By applying silicon photonic technology in microwave photonics, on-chip integration of microwave photonic systems could be implemented with improved performance including a much smaller size, better stability and lower power consumption. This thesis focuses on developing silicon-based photonic integrated circuits for microwave photonic applications. Two types of silicon-based on-chip devices, waveguide Bragg gratings and optical micro-cavity resonators, are designed, developed, and characterized, and the use of the developed devices in microwave photonic applications is studied. After an introduction to silicon photonics and microwave photonics in Chapter 1 and an overview of microwave photonic signal generation and processing in Chapter 2, in Chapter 3 a silicon-based on-chip phase-shifted waveguide Bragg grating (PS-WBG) is designed, fabricated and characterized, and its use for the implementation of a photonic temporal differentiator is experimentally demonstrated. To have a waveguide grating that is wavelength tunable, in Chapter 4 a tunable waveguide grating is proposed by incorporating a PN junction across the waveguide grating, to use the free-carrier plasma dispersion effect in silicon to achieve wavelength tuning. The use of a pair of wavelength-tunable waveguide gratings to form a wavelength-tunable Fabry-Perot resonator for microwave photonic signal processing is studied. Thanks to its electrical tunability, a high-speed electro-optic modulator, a tunable fractional-order photonic temporal differentiator and a tunable optical delay line are experimentally demonstrated. To increase the bandwidth of a waveguide grating, in Chapter 5 a linearly chirped waveguide Bragg grating (LC-WBG) is designed, fabricated and evaluated. By incorporating two LC-WBGs in two arms of a Mach-Zehnder interferometer (MZI) structure, an on-chip optical spectral shaper is produced, which is used in a photonic microwave waveform generation system based on spectral-shaping and wavelength-to-time (SS-WTT) mapping for linearly chirped microwave waveform (LCMW) generation. To enable the LC-WBG to be electrically tuned, in Chapter 6 a lateral PN junction is introduced in the grating and thus an electrically tunable LC-WBG is realized. By incorporating two tunable LC-WBGs in a Michelson interferometer structure, an electrically tunable optical spectral shaper is made. By applying the fabricated spectral shaper in an SS-WTT mapping system, a continuously tunable LCMW is experimentally generated. Compared with a waveguide Bragg grating device, an on-chip optical micro-cavity resonator usually has a much smaller dimension, which is of help to increase the integration density and reduce the power consumption. Different on-chip optical micro-cavity resonators are studied in this thesis. In Chapter 7, an on-chip symmetric MZI incorporating multiple cascaded microring resonators is proposed. By controlling the radii of the rings, the MZI could be designed to have a spectral response with a linearly-varying free spectral range (FSR), which could be used in photonic generation of an LCMW, and to have a multi-channel spectral response with identical channel spacing, which could be used in the implementation of an independently tunable multi-channel fractional-order temporal differentiator. To further reduce the footprint of an optical micro-cavity resonator, in Chapter 8 an ultra-compact microdisk resonator (MDR) with a single-mode operation and an ultra-high Q-factor is proposed, fabricated and evaluated, and its use for the implementation of a microwave photonic filter and an optical delay line is experimentally demonstrated. To enable the MDR to be electrically tunable, in Chapter 9 an electrically tunable MDR is realized by incorporating a lateral PN junction in the disk. The use of the fabricated MDR in microwave photonic applications such as a high-speed electro-optic modulator, a tunable photonic temporal differentiator and a tunable optical delay line is experimentally demonstrated.

Book excerpt: "This thesis concerns all-optical signal processing and microwave photonics techniques basedon integrated silicon photonics devices. Firstly, we have designed and characterized a typeof integrated 2R regenerator for restoring 10 Gb/s on-off keying signals in simulation, withprospect for simultaneous multi-channel 2R regeneration for even higher speed. Furthermore,we demonstrate photonic generation of chirped microwave pulses using an integratedsilicon distributed Fabry-Pérot cavity as a spectral shaper, with the possibility of a ultimate'blackbox' solution. This two demonstrations investigate in scaling up the integrationlevel of silicon device so as to escalate the usabilities and functionalities of all-optical signalprocessing and microwave photonic subsystems. Secondly, we have designed and fabricateda mode-selective nonlinear silicon device and proposed a method of harnessing nonlinearoptical effects in a mode-selective manner to realize simultaneous multi-channel broadbandwavelength conversion and signal regeneration for 10 Gb/s OOK signals. Using the sametechnique, we succeed in demonstrating simultaneous multi-channel RF spectrum analyzerfor 640 GHz and 160 GHz optical waveforms in a single multi-mode waveguide. We believethat the method of harnessing nonlinear optics in a mode-selective manner has potentialto scale to a higher number of channels and opens up a new degree of freedom in realizingvarious multi-channel all-optical signal processing and microwave photonics functionalitiesin an integrated photonic device." --

Book excerpt: The use of optical technology can provide unprecedented performance to the generation, distribution, and processing of microwave. Recently, on-chip microwave photonics (MWP) has gained significant interests for its numerous advantages, such as robustness, reconfigurability as well as reduction of size, weight, cost, and power consumption. In this chapter, we review our recent progress in ultracompact microwave photonic signal processing using silicon nanophotonic devices. Using the fabricated silicon waveguide, silicon microring resonators (MRRs) and silicon photonic crystal nanocavities, we demonstrate on-chip analog signal transmission, optically controlled tunable MWP filter, and ultra-high peak rejection notch MWP filter. The performance of analog links and the responses of MWP filters are evaluated in the experiment. In addition, microwave signal multiplication and modulation are also demonstrated based on a silicon Mach-Zehnder modulator in the experiment with favorable operation performance. The demonstrated on-chip analog links, MWP filters, microwave signal multiplication/modulation may help understand on-chip analog signaling and expand novel functionalities of MWP signal processing.

Available in PDF, EPUB and Kindle. Book excerpt: Microwave photonics is broadly defined as the study of optical devices operating in the microwave to millimeter wave spectrum, and interest in this field is continually driven by the need for higher electrical frequencies and larger signal bandwidths. However, electronic systems designed to meet these specifications are becoming increasingly challenging to create, while their microwave photonic counterparts offer a larger bandwidth, lower power consumption, higher linearity, and smaller footprint. Thus, microwave photonic systems are an attractive solution for challenging problems in the domain of high-speed electronics. This thesis will examine a specific component of a microwave photonic system, a frequency down-converter. This device takes two electronic input signals and outputs the difference between the two input frequencies. To date, all demonstrations of a photonic microwave frequency down-converter have been based on bulk optical devices that limit its deployability to a real-world application due to a large footprint. However, recent advances to silicon photonic fabrication processes stand to improve the performance and enable the mass-production of many different microwave photonic systems including a frequency down-converter. In this thesis, a library of passive CMOS-compatible silicon photonic components for microwave photonic systems was developed. Additionally, a high-saturation power germanium-on-silicon photodetector showing a 70% improvement in photocurrent generation under high incident powers, and a depletion mode optical phase shifter with a V[subscript [pi]]L of 0.9 V xcm and an electro-optical bandwidth of several gigahertz were designed and tested. Finally, all of these components were assembled in a novel architecture to create an integrated silicon photonic microwave frequency down-converter. Initial measurements of this structure showed an electrical-to-electrical conversion efficiency of -42 dB and a suppression of spurious frequencies of approximately 15 dB.
