ABSTRACT:
A photoreceiver for frequency-modulated optical signals. The photoreceiver is formed of a semiconductor laser of the FABRY-PEROT type, wherein one of the faces thereof which receives a frequency modulated light beam is given an antireflection treatment. The voltage at the laser terminals is also tapped. Such a device finds particular application to optical telecommunication systems.
