Abstract
Provided for herein is random number generator that includes a vertical cavity surface emitting laser, VCSEL, a mode separator and a photodetector, the random number generator further comprising a power source to drive the VCSEL in direct modulation mode. The VCSEL is adapted to emit, from an emitting section into space outside of a VCSEL cavity, laser light with two distinct laser modes of random relative strength that can propagate in a propagation direction away from the emitting section. The mode separator is arranged between the photodetector and the VCSEL in propagation direction to separate the two distinct laser modes from each other and to transmit one of the distinct laser modes to the photodetector.
