Abstract
Photodiode detectors having narrow spectral response without use of external filters have been fabricated. Use of high resistivity semi‐insulating GaAs in the construction of such diodes makes it possible to modulate the spectral response by application of moderate values of reverse bias. A device is described whose spectral response is expanded from a half‐width of ∼ 200 Å to typical broad‐band characteristics under 30 V reverse bias.Keywords
