Paper Abstract

This paper presents an electronic circuit which can be used as a very fast electronic 'fuse' in laser diode drivers. The main causes of damage of laser diodes are either unexpected electrical transients or catastrophic facet damage occurring at optical power density exceeding 106 W/cm2. Both can be induced by electromagnetic interference in typical drivers with automatic power control. Presented scheme has a reaction time about 2 microsecond(s) , which reduces the possibility of over driving the laser diode.
