Paper Abstract
We demonstrate a wavelength-selective photodetector that combines a Fabry-Perot filtering-cavity (FPC) with a taper absorption-cavity (TAC). The taper cavity shows non-resonant effect but exhibits absorption enhancement effect, so that high-speed, high quantum efficiency, wide tuning range and ultra-narrow spectral linewidth can be achieved simultaneously. Device performance was theoretically investigated by including key factors such as taper angle, finite-size diffracting-beam input, and lateral walk-off in the taper cavity. The device was fabricated by bonding a GaAs-based FPC, which can be tuned via thermal-optic effect, with an InP-based TAC. The experiment results of the devices were reported in another paper.
