Low-reflection photonic-crystal taper for efficient coupling between guide sections of arbitrary widths.
We design and fabricate a new taper structure for adiabatic mode transformation in two-dimensional photonic-crystal waveguides patterned into a GaInAsP confining layer. The taper efficiency is validated by measurement of a reduction of the reflection between an access ridge and a photonic-crystal guide with one missing row from 6% to less than 1%. This taper is then incorporated into a 60 degre...
متن کاملDesign and Analysis of a Novel Hexagonal Shaped Channel Drop Filter Based on Two-Dimensional Photonic Crystals
In this paper a new optical channel drop filter (CDF) based on two dimensional (2-D) photonic crystals (PhC) with hexagonal shaped structure is proposed and numerically demonstrated by using the finite-difference-time-domain (FDTD) and plane-wave-expansion (PWE) techniques. Photonic crystals (PhCs) are artificial dielectric nanostructure materials in which a periodic modulation of the material ...
متن کاملParallel microgenetic algorithm design for photonic crystal and waveguide structures.
We have developed a powerful parallel genetic algorithm design tool for photonic crystal and waveguide structures. The tool employs a small-population-size genetic algorithm (microgenetic algorithm) for global optimization and a two-dimensional finite-difference time-domain method to rigorously design and optimize the performance of photonic devices. We discuss the implementation and performanc...
متن کاملTwo-curve-shaped biosensor using photonic crystal nano-ring resonators
We design a novel nano-ring resonator using two-dimensional photonic crystal (2D-PhC), for bio-sensing applications. The structure of biosensor is created by two-curve-shaped ring resonator which sandwiched by two waveguides. These are configured by removing one row of air holes. The refractive index of sensing hole is changed by binding an analyte. Hence, intensity of the transmission spectrum...
متن کاملمقایسه نتایج شبیهسازی بلور فوتونی با استفاده از روش FDTD دوبعدی بهبودیافته و FDTD سهبعدی
The accuracy of improved two dimensional finite difference time domain method (2D FDTD) is verified by comparing with 3D FDTD method and experimental data. The optimized 60° photonic crystal waveguide bend, used in this study as a test case, is composed of InPGaAs/InP material and air holes and TE polarization is considered. The photonic crystal waveguide bend transmission data was measured...
