Abstract Details

2005, MS, University of Cincinnati, Engineering : Electrical Engineering.
Optical properties of photonic crystal (PC) structures have attracted great interest in research area and industry field because of its capability to guide and control light propagation in compact device with feature sizes comparable to light wavelength. Optical filters are essential components of photonic integrated circuits and Wavelength Division Multiplexer (WDM). In this thesis, a WDM is designed based on PC with a defect gap mode. We first describe the design and simulation of the photonic band gap (PBG) in a perfect triangular lattice of air holes in Si. Then based on Silicon-On-Insulator (SOI) slab model, we will introduce pass band in the photonic band gap by moving the two slabs of PBG structure apart some distance, which results in a photonic crystal Fabry-Perot filter in an SOI waveguide. A WDM architecture with 3 channels is designed based on this kind of PC filter last and selective wavelength add/drop function in 2 channel filters is simulated with no more than 1.55dB loss using Finite-Difference Time-Domain (FDTD). PC has strong effects on optical group velocity. In addition to filter response, the dispersion properties in time domain are studied with FDTD. The dispersion was found to be about 45ps/(mm·ìm) through the passband around 1.55ìm, but due to the small length of the filter, it should have nominal effects for signal propagation up to the bit rate of 4000Gb/s.
