Photonic Systems, Inc., founded to address the communications industry's need for low-cost, high-performance fiber-optic components, introduced a new Modulator Bias Controller. The PSI 0202 Modulator Bias Controller accurately maintains a specific bias point on a Mach-Zehnder modulator's transfer function curve.
Control switches on the front panel allow the user to select between Manual and Automatic bias control modes, and select from among the quadrature, max and min points on the transfer function curve. Bias accuracy is better than 2° typically, and better than 0.5° if the high accuracy option is selected. A readout displays the bias voltage and modulator optical output power at the bias voltage.
Set-up is quick and easy because the optical tap coupler and photodetector are contained in the controller box. Three controllers fit across one shelf of a standard 19-inch rack, facilitating the installation of controllers for multiple modulators. An OEM version is also available.
