چکیده

With designing air pads on silicon-on-insulator (SOI) wafer periodically as a cellular structure, a 1×2 photonic band gap (PBG) beam splitter is proposed in this article . We study the characteristics of the designed 1×2 SOI PBG beam splitter and simulate the relationship of the two output power with the launching wavelengths. We use finite-difference-time-domain (FDTD) as simulation technique. The propagation of the light and the spectral response are simulated. The device we designed has the total length 4.46 μm and the total width 7 μm.

Design 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...

A New Design of Photonic Crystal Filter and Power Splitter Based on Ring Resonators

Here, we propose an optical filter and an optical power splitter based on two-dimensionalphotonic crystal all circular ring resonators. These structures are made of a square lattice ofsilicon rods with the refractive index n1=3.464 surrounded by air (with refractive indexn2=1). First, we have designed the filter and by using that, we designed a power splitter. Thetransmission efficiency and Qua...

Design of a High-Bandwidth Y-Shaped Photonic Crystal Power Splitter for TE Modes

In this paper, a Y-shaped power splitter based on a two dimensional photonic crystal (PhC) for TE modes is designed and optimized. A triangular lattice of air holes is used for Y-shaped power divider. For analyzing these structures, plane wave expansion (PWE) and finite difference time domain (FDTD) methods are used. The simulation results show that more than 98% of the input power is transmitt...

All-Optical Reconfigurable-Tunable 1×N Power Splitter Using Soliton Breakup

In this paper, we numerically simulated a glass-based all-optical 1×N power splitter with eleven different configurations using soliton breakup in a nonlinear medium. It is shown that in addition to reconfigurability of the proposed splitter, its power splitting ratio is tunable up to some extent values too. Nonlinear semivectorial iterative finite difference beam propagation method (IFD-...

Room Temperature Photonic Crystal Defect Lasers at Near-Infrared Wavelengths in InGaAsP

Room temperature lasing from optically pumped single defects in a two-dimensional (2-D) photonic bandgap (PBG) crystal is demonstrated. The high-Q optical microcavities are formed by etching a triangular array of air holes into a halfwavelength thick multiquantum-well waveguide. Defects in the 2-D photonic crystal are used to support highly localized optical modes with volumes ranging from 2 to...
