Abstract:

We report theoretical and experimental investigations of infrared absorption characteristics for PbSe colloidal quantum dots in defect-free photonic crystal PC cavities, via Fano resonances. Angle and polarization independent transmission and absorption are feasible for surface normal incident beams with dispersion engineered modal design. Experimental demonstration was done on patterned single crystalline silicon nanomembranes SiNMs transferred on glass and on flexible PET substrates, with PbSe QDs backfilled into the air holes of the patterned SiNMs. These findings enable the design of spectrally selective photodetectors at near infrared regime with the desired angle and polarization properties.
