摘要:

Simple photoconductive optical detectors for 1.55 &mgr;m wavelength have been fabricated on InGaAsP grown by He-plasma assisted molecular beam epitaxy. Characterization of the photodetectors shows that their speed is determined by the free carrier trapping time, with a full width at half-maximum impulse response of approximately 6 ps. ©1998 American Institute of Physics.
