Abstract

An optical power splitter and a spot-size converter in silicon-based photonic crystals have been proposed and demonstrated. The optical power splitter is an extension of conventional 1x2 photonic crystal power splitter to 1x3 and 1x5 scales while the spot-size converter is formed by removing several rows of dielectric rods in different amount from the photonic crystals. The device functionality and performance have been numerically investigated and simulated by finite-difference time-domain method.
