Abstract
A monolithically integrated wire grid polarizer and quantum dot infrared photodetector is reported. The photodetector array is integrated with a single large area aluminum wire grid polarizer that was fabricated using standard photolithographic procedures. The polarizer has period of 4μm and a 50% duty cycle. The device has an extinction ratio of 3dB for normal incidence long wavelength infrared radiation.
