Abstract :
We demonstrate a tunable long wavelength vertical-cavity photodetector which is fabricated by bonding a GaAs-based tunable filter with an InP-based absorption structure. The wavelength tuning range of 10.5 nm was achieved via thermal-optic effect. The external quantum efficiency of about 22%, the spectral linewidth as narrow as 0.6 nm, and the 3-dB bandwidth of 12 GHz were obtained in the device
