Nanosecond Time Responses of Different Indium Antimonide Photodetectors
The time response of an InSb PEM Photodetector*  was recently observed to be approximately 18 nsec  by means of a new type nanosecond light source . This response is considerably faster than that claimed by the producer and agrees with predictions derived from steady-state investigations , Spectral measurements with the PEM show a slower decay in the infrared which is possibly the result of a slower IR decay of the detector but may also result from an IR tail of the light pulse, a possibility which has not yet been confirmed (see Fig. 1).
