Design of plasmonic photonic crystal resonant cavities for polarization sensitive infrared photodetectors.
نویسندگان
چکیده
We design a polarization-sensitive resonator for use in mid-infrared photodetectors, utilizing a photonic crystal cavity and a single or double-metal plasmonic waveguide to achieve enhanced detector efficiency due to superior optical confinement within the active region. As the cavity is highly frequency and polarization-sensitive, this resonator structure could be used in chip-based infrared spectrometers and cameras that can distinguish among different materials and temperatures to a high degree of precision.

Spectrally Selective Infrared Absorption Enhancement in Photonic Crystal Cavities
Infrared photodetectors with spectrally selective response are highly desirable for applications such as hyper-spectral imaging and gas sensing. Owing to the ability of photonic density of states modification and dispersion engineering, photonic crystals appear to be one of the most promising platforms for infrared photodetectors with spectrally-selective absorption enhancement. We report here ...
متن کاملDesign of Photonic Crystal Polarization Splitter on InP Substrate
In this article, we suggested a novel design of polarization splitter based on coupler waveguide on InP substrate at 1.55mm wavelength. Photonic crystal structure is consisted of two dimensional (2D) air holes embedded in InP/InGaAsP material with an effective refractive index of 3.2634 which is arranged in a hexagonal lattice. The photonic band gap (PBG) of this structure is determined using t...

متن کاملDesign of an efficient terahertz source using triply resonant nonlinear photonic crystal cavities.
We propose a scheme for efficient cavity-enhanced nonlinear THz generation via difference-frequency generation (DFG) processes using a triply resonant system based on photonic crystal cavities. We show that high nonlinear overlap can be achieved by coupling a THz cavity to a doubly-resonant, dual-polarization near-infrared (e.g. telecom band) photonic-crystal nanobeam cavity, allowing the mixin...

In this paper design and two dimensional (2D) simulation of a photonic crystal highly sensitive temperature sensor is presented. The 2D simulations are based on finite-difference time-domain (FDTD) method and are done using Rsoft software. The device is constructed using a cavity filled with the distilled water located in the center of the photonic crystal waveguide. The operation of the propos...
