Abstract
The photodetection sensitivity of the Avalanche Breakdown (AB) photodetector at λ=151μm has been increased by shaping the detector element so as to trap incident radiation by total internal reflection. Pulsed laser signals have been detected at powers as low as 5 x 10-15 W, corresponding to the arrival at the detector of only 4-5 photons during each 300 ns laser pulse. Several mechanisms are considered.
