Balanced detection technique to measure small changes in transmission

Not Accessible

Your library or personal account may give you access

Abstract

A novel technique to measure changes in optical transmission of better than 10−3 with time resolution of better than 10 ns is discussed. The photocurrent from two photodiodes is subtracted with a balanced detection circuit to eliminate the common signal; carrier-induced change in absorption for a semiconductor single quantum well produces a large differential signal.
