Abstract
An effective and robust method for generating random bits from random time intervals between quantum jumps of optical field is proposed and experimentally tested with spontaneous switchings in a bistable vertical-cavity surface-emitting laser. This algorithm allows one to avoid the problem of biasing in the output bit stream as well as to obtain low correlation between generated bits. A comprehensive comparative statistical analysis of different methods of extraction of random bits from experimentally measured time intervals between spontaneous polarization switchings in a bistable vertical-cavity surface-emitting laser shows the advantage of the proposed method.
