Available in PDF, EPUB and Kindle. Book excerpt: Processing of high-speed data using optical signals is a promising approach for tackling the bandwidth and speed challenges of today's electronics. Realization of complex optical signal processing functionalities seems more possible than any time before, thanks to the recent achievements in silicon photonics towards large-scale photonic integration. In this Ph. D. work, a novel thermal reconfiguration technology is proposed and experimentally demonstrated for silicon photonics that is compact, low-loss, low-power, fast, with a large tuning-range. These properties are all required for large-scale optical signal processing and had not been simultaneously achieved in a single device technology prior to this work. This device technology is applied to a new class of resonator-based devices for reconfigurable nonlinear optical signal processing. For the first time, we have demonstrated the possibility of resonance wavelength tuning of individual resonances and their coupling coefficients. Using this new device concept, we have demonstrated tunable wavelength-conversion through four-wave mixing in a resonator-based silicon device for the first time.

This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: High index-contrast nanophotonic devices are key components for future board-to-board and chip-to-chip optical interconnects: The strong confinement of light enables dense integration, and nonlinear effects can be exploited at low power levels. Cheap large-scale production is possible by using highly parallel microfabrication techniques, and semiconductor-based nanophotonic devices can be integrated together with electronic circuitry on a common chip. Particularly intense research is carried out to realise optical devices on silicon substrates, using mature complementary metal-oxide-semiconductor (CMOS) fabrication techniques.This book discusses the modelling, fabrication and characterization of linear and nonlinear nanophotonic devices. Roughness-related scattering loss in high index-contrast waveguides is investigated both theoretically and experimentally, and methods of loss reduction are developed. Novel silicon-based devices for electro-optic modulation and for all-optical signal processing are presented. Nonlinear dynamics in active quantum-dot devices are studied, and resonant field enhancement is exploited to improve the efficiency of nonlinear interaction.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Processing of high speed optical signals in the optical domain, referred to as optical signal processing, is required for many applications in the telecommunication systems and networks. Many optical signal processing techniques have been studied in the literature where most of them are based on nonlinear optics such as 2nd order and 3rd order nonlinear effects. A wide range of nonlinear media are used for performing these nonlinear optical signal processing applications such as optical fibres, semiconductor optical amplifiers, and different types of optical waveguides. In this thesis, we use nonlinear optics to perform nonlinear optical signal processing and microwave photonics applications. First we propose and experimentally demonstrate an optical signal processing module that will be used for recognition of spectral amplitude code (SAC) labels in optical packet-switched networks. We use the nonlinear effect FWM in a highly nonlinear fibre (HNLF) for generation of a unique FWM idler for each SAC label referred to as a label identifier (LI). A serial array of fibre Bragg gratings is then used to reflect the LI wavelengths. Each LI is associated with a unique amount of delay between two optical signals received at two photodiodes. Label recognition is then achieved by measuring this unique time delay. An experiment is conducted where two variable-length data packets are transmitted over a 50-km dispersion-compensated span of fibre and switched at a forwarding node. The SAC labels are successfully recognized, and we obtain error-free transmission for the switched packets with less than 0.3-dB penalty. Then using FWM in a HNLF and also a programmable planar lightwave circuit (PLC) we propose and experimentally demonstrate the all-optical reconfigurable time slot interchange (TSI) of individual bits at 40 Gb/s. The PLC is used to generate different control signals (masks) that determine which bits undergo TSI. By programming the PLC to generate two different masks, two different TSI patterns are obtained. TSI is achieved using FWM between the data signal and the desired mask with bidirectional propagation in the HNLF. Error-free operation is obtained for both of the TSI patterns, with a power penalty of less than 5.2 dB, at a bit error rate of 10-9.Next, we use a low-stress silicon-rich nitride waveguide as the nonlinear medium to perform two different applications based on XPM. The waveguide is engineered to display flat and low dispersion over the entire C+L bands. First, we demonstrate wavelength conversion of 10 Gb/s signals across the C band and obtain error free operation. We also demonstrate ultra broadband wavelength conversion over 300 nm from the O-band to the L-band. Second, we highlight the use of SixNy waveguides for nonlinear MWP. We report the first demonstration of an XPM-based radio-frequency (RF) spectrum analyzer of optical signals using an integrated silicon nitride waveguide. Measurements show a bandwidth of at least 560 GHz for our RF-spectrum analyzer. RF-spectra measurements for pulse trains at rates from ~ 10 GHz to ~ 160 GHz are demonstrated. These results show that the silicon nitride technology has a competitive performance for realizing high-speed optical processing of telecom signals." --

This book was released on 2012 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Silicon is the material that has become the basic and most important platform for the development of microelectronics in the past few decades. Silicon is not only the dominant semiconductor material for CMOS technology, but also a good candidate for optical high-speed interconnections and signal processing in 1.5-[mu]m telecommunication windows due to its high refractive index, large bandgap and strong nonlinearity. In parallel, silicon-based optical biosensing devices have recently been developed by taking advantage of the optical properties of the nanostructured silicon devices. First, we studied the nonlinear dispersion in a silicon waveguide using an optical pump-probe setup. The pump and the probe signals are co-propagating in the waveguide, and we observed the nonlinear dispersion (Kerr effect) resulting from cross-phase modulation. The nonlinear dispersion produced polarization rotation in the probe transmission, and therefore all-optical modulation was achieved with less than one picosecond switching window. Next, we studied the slow-light dispersion in a one-dimensional photonic crystal based microring resonator. We first designed and optimized the waveguide-to-resonator coupling in the high-dispersion regime near the band-edge. Then, we observed the slow-light effect with a maximum measured group index of ~20. Because of the slow-light effect, the free spectral range (FSR) is reduced, and quality factor (Q-factor) is increased in the transmission spectrum. With this approach, we can reduce the size of the ring resonator while maintaining a large FSR. Inspired by the unique standing wave resonance profile patterns, we designed a novel multi-waveguide-coupled microring. Depending on the relative azimuthal position of the waveguides, we can selectively filter a set of resonances for signal processing applications. The bandwidth of the device can be improved by employing a chirped two-dimensional photonic crystal defect waveguide. Last, we designed a novel two-dimensional silicon photonic crystal based air slot microcavities. The slot effect enables tight optical confinement in the 100-nm-wide air slot. Because of this strong optical confinement, this device is highly sensitive to the refractive index perturbation in the air slot region. With an active volume of ~0.08[mu]m3 and the device is capable of detecting nano-particle with diameters well below 100 nm"--Page vi-vii.
