OZ Optics’ MBC-HER high extinction ratio, full-function, miniature OEM version modulator bias controller is designed to be used with a single MZ modulator for high extinction ratio applications.

The MBC modulator bias controller not only can be used to lock the working point of the modulator at the positive slope quadrature (quad+), negative slope quadrature (quad-), null or peak points of its characteristic curve, but also features an extremely small pilot tone which allows for an exceptionally high extinction ratio of >45 dB, depending on the limits of the modulator. The locking modes and slopes are selectable by changing the jumper positions on the PCB. A pigtailed photodetector is included. An external photodetector may also be used.
