Abstract In this work we propose a novel design of 5-channel DWDM demultiplexer and, numerical analysis of its optimal design parameters and device performance is presented. Photonic crystal hexagonal ring resonators of airholes on a silicon slab are used as channel drop filters. Wavelength controlling is achieved by fine tuning of coupling holes outside each ring resonator. For the proposed design, the resolved wavelengths are in the range of 1535 to 1539nm, where Erbium Doped Fiber Amplifiers are applicable. The average coupling efficiency and cross talk are found to be 72.4% and -18.31dB, respectively. Photonic bandgap computation is performed by using plane wave expansion method and spectral characteristics are obtained by applying 3D finite difference time domain method.

Abstract Increasing the speed of operation in all optical signal processing is very important. For reaching this goal one needs high speed optical devices. Optical half adders are one of the important building blocks required in optical processing. In this paper an optical half adder was proposed by combining nonlinear photonic crystal ring resonators with optical waveguides. Finite difference time domain method wase used for simulating the final structure. The simulation results confirmed that the rise time for the proposed structure is about 1 ps.

AbstractGraphene has been widely used in silicon-based optical modulators for its ultra-broadband light absorption and ultrafast optoelectronic response. By incorporating graphene and slow-light silicon photonic crystal waveguide (PhCW), here we propose and experimentally demonstrate a unique double-layer graphene electro-absorption modulator in telecommunication applications. The modulator exhibits a modulation depth of 0.5 dB/μm with a bandwidth of 13.6 GHz, while graphene coverage length is only 1.2 μm in simulations. We also fabricated the graphene modulator on silicon platform, and the device achieved a modulation bandwidth at 12 GHz. The proposed graphene-PhCW modulator may have potentials in the applications of on-chip interconnections.
