Book excerpt: This thesis establishes a mathematical, physical and experimental framework for description, characterization, and application of semiconductor plasmonic properties. Plasmonic phenomena in semiconductors are found in the Terahertz and far-infrared domain, where they have the potential to improve sensors or be the basis of novel devices. III-V semiconductor samples (GaAs, InP, InSb, and InAs) with various doping were analyzed spectroscopically in broad spectral range. Fourier Transform Infrared Spectroscopy together with Terahertz time-domain spectroscopy were used for characterization of the free carrier (plasmonic) and lattice (phononic) optical properties of the samples. The Drude-Lorentz model was used to describe these properties, with the addition of magneto-optical (MO) effects. High mobility semiconductors (InSb and InAs) exhibit huge free carrier magneto-optical effect for small external magnetic field. These measurements were compared to electric Hall effect measurement using Van der Pauw method. Based on the spectroscopic and MO characterization of the samples, the applicability of semiconductor as plasmonic materials is discussed. Huge advantage of semiconductors is the tunability their plasmonic properties. Three methods of controlling the plasmonic behavior of semiconductors were analyzed: Shifting of plasma frequency to higher frequencies by increasing of n-type doping concentration. Modification of the material permittivity (conductivity) tensor spectra by the external magnetic field. Shifting of plasmonic resonance by generation of nanogratings in the material, either by carrier concentration modulation by interference light illumination (sinusoidal grating) or by lithography (lamellar grating). The effective medium approximation of nanogratings was verified using Rigorous Coupled Wave Analysis. An experimental application of widely tunable THz surface plasmon resonance sensor on semiconductors is presented. Generation of surface plasmon polariton at the interface between undoped InSb(InAs) and dielectric is experimentally demonstrated. This sensor has the added functionality of strong magnetic tuning. The applicability of this sensor is discussed, along with analysis of different sensor architecture.

Available in PDF, EPUB and Kindle. Book excerpt: Metal-semiconductor nanostructures represent an important new class of materials employed in designing advanced optoelectronic and nanophotonic devices, such as plasmonic nanolasers, plasmon-enhanced light-emitting diodes and solar cells, plasmonic emitters of single photons, and quantum devices operating in infrared and terahertz domains. The combination of surface plasmon resonances in conducting structures, providing strong concentration of an electromagnetic optical field nearby, with sharp optical resonances in semiconductors, which are highly sensitive to external electromagnetic fields, creates a platform to control light on the nanoscale. The design of the composite metal-semiconductor system imposes the consideration of both the plasmonic resonances in metal and the optical transitions in semiconductors - a key issue being their resonant interaction providing a coupling regime. In this book the reader will find descriptions of electrodynamics of conducting structures, quantum physics of semiconductor nanostructures, and guidelines for advanced engineering of metal-semiconductor composites. These constituents form together the physical basics of the metal-semiconductor plasmonics, underlying many effective practical applications. The list of covered topics also includes the review of recent results, such as the achievement of a strong coupling regime, and the preservation of non-classical statistics of photons in plasmonic cavities combined with semiconductor nanostructures.

Book excerpt: Current developments in optical technologies are being directed toward nanoscale devices with subwavelength dimensions, in which photons are manipulated on the nanoscale. Although light is clearly the fastest means to send information to and from the nanoscale, there is a fundamental incompatibility between light at the microscale and devices and processes at the nanoscale. Nanostructured metals which support surface plasmon modes can concentrate electromagnetic (EM) fields to a small fraction of a wavelength while enhancing local field strengths by several orders of magnitude. For this reason, plasmonic nanostructures can serve as optical couplers across the nano–micro interface: metal–dielectric and metal–semiconductor nanostructures can act as optical nanoantennae and enhance light matter coupling in nanoscale devices. This book describes how one can fully integrate plasmonic nanostructures into dielectric, semiconductor, and molecular photonic devices, for guiding photons across the nano–micro interface and for detecting molecules with unsurpassed sensitivity. ·Nanophotonics and Nanoplasmonics·Metamaterials and negative-index materials·Plasmon-enhanced sensing and spectroscopy·Imaging and sensing on the nanoscale·Metal Optics

Download or read book SEMICONDUCTOR BASED HYBRID PLASMONICS written by Mohamed Eldlio and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the typical size of electronic devices approaches the nanometer range, the size mismatch between such devices and optical components-which are typically in the micrometer range-poses a challenge for the two technologies integration on the same chip. For conventional dielectric waveguides, the mode cannot be confined to sizes smaller than half the wavelength due to the diffraction limitation. One possible and promising technological development to resolve this issue is the so-called surface plasmon polaritons (SPPs). Given the growing importance of optical plasmonics in semiconductors for a wide variety of applications; it is essential to devise a modal which is directly interpretable in physical terms. In the optical regime metals have a complex permittivity, which means that SPPs suffer from large propagation loss. To mitigate this loss, semiconductors can be used instead of metal, but their application is limited in the far-infrared regime because the permittivity has a negative real part. Semiconductors are therefore promising materials for developing efficient terahertz (THz) waveguides. The frequency of a THz wave occupies the electromagnetic spectra between microwave and infrared ranges and acts as a bridge. As a result THz semiconductor-based hybrid plasmonics has become one of the most promising applications in the plasmonics field. This thesis presents a theoretical study and develops the physics and mathematics of SPPs in semiconductors at optical frequencies, taking into account the different properties of these semiconductors. It also investigates the modal properties of a hybrid plasmonic waveguide operating at a THz regime in different types of structures. The analytical results are compared to conventional hybrid waveguides previously reported. Numerical solutions are also obtained for proposed novel hybrid terahertz plasmonic waveguide structures. Moreover, a theoretically study of the optical properties of a superconductorinsulator- superconductor waveguide both at THz and telecommunication frequencies were performed. These novel studies provide insight into the fundamental nature of optical plasmon semiconductors. A primary focus of the thesis is geometries which exhibit the capability of supporting SPPs.
