Abstract :
Theoretical and experimental research results on the characteristics of photonic crystal quantum dot infrared photodetectors are presented. The surface normal absorption power in a single defect photonic crystal cavity for different absorption values and the absorption enhancement factor for different absorption values in single defect and defect free cavities are investigated. Current-voltage characteristics at different temperatures and the spectral responses of the devices with and without photonic crystal cavities are measured.
