Modulator Bias Controller
Oct 2007

BESANCON, France, Oct. 15, 2007 -- Photline Technologies said its new MBC-1001 is a modulator bias controller designed to stabilize the operating point of LiNb03 (lithium niobate) crystal Mach-Zehnder modulators used in high-speed optical communication systems.

The MBC-1001's new and unique feature, according to Photline, is the continuous tuning of the operating point over the transfer function of the modulator, when classical systems only offer a limited choice of points (typically: min., max., quad+, quad-). This capability is especially useful to accommodate the large variety of modulation formats used in new generation telecom systems. It allows also to compensate for the slight bias shift often caused by the modulators internal monitoring photodiodes.

It is compatible with all Mach-Zehnder type modulators and can operate with the photocurrent provided by an internal monitoring photodiode or by an external tap one.
