Paper Abstract

This paper describes the realization of high quality-factor (Q-factor) and high transmission photonic crystal micro-cavity and extended cavity structures embedded in photonic wire waveguides. Q-factor of as much as 16600 have been achieved in micro-cavities with transmission of more than 80%. We have also fabricated an 8 μm long extended cavity with a measured Q-factor of 5100 with normalised transmission of around 67%. Three-dimensional (3D) Finite Difference Time Domain (FDTD) computation has been used to simulate the devices. Comparison of the simulation and measured result shows reasonably good agreement.
