PSI - 2600-11 CONTROLLER BOARD

The PSI—2600-11 Photonic Controller Board offers simple turn-up and test of optical systems which require a semiconductor laser light source. This product offers a single solution for optical power, thermo-electric and modulator bias control circuitry typically found in fiber optic transmitters.

The basic controller board offers feedback mechanisms for accurately monitoring laser power through the laser’s internal back facet photodetector. This provides stable optical output power over system lifetime and operating temperature range. Also included is a high accuracy controller for the laser diode Peltier thermoelectric cooler (TEC). The user may adjust precise optical power and laser temperature operating points which the PSI-2600-11 will maintain over the device operating lifetime.

Also included is a facility for the PSI-0204-11 modulator bias controller. This device controls the operating bias point for a Lithium Niobate (LiNbO3) external modulator and provides precise tracking on a modulator’s transfer function for analog or DPSK data transmission systems. When used together, the PSI-2600-11 laser control board and PSI-0204-11 modulator bias controller provides all electronic circuitry needed for an externally modulated photonic transmitter.
