Abstract
We have characterized the optical modes present in a two-dimensional photonic crystal single defectcavityfabricated in an InP/In 0.53 Ga 0.47 As/InP double heterostructure thin film on a glass slide. The cavity resonance was tuned to different frequencies in the 1.55 μm spectral region. Radiation losses and material absorption influence the measured value of cavity quality factor Q. We separated these two loss mechanisms by performing a curve fit of the loss rate 1/Q versus the wavelength-dependent absorption coefficient of In 0.53 Ga 0.47 As . By extrapolating this curve to zero absorption, the radiation loss rate 1/Q rad is obtained.This publication has 18 references indexed in Scilit:
