PSI-2600-11
Photonic Controller Board
Product Description
The PSI—2600-11 Photonic Controller Board offers simple turn-up and test of optical systems which require asemiconductor laser light source. This product offers auniversal replacement for power, thermo-electric andmodulator 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 andoperating temperature range. Also included is a highaccuracy 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.
Product Benefits
Simple control of common 14 pin DIL Laser packages
Flexible application space: use in broad range of external modulation fiber optic links, test systems
or other laser light sources
TEC control over wide temperature range
Back-facet photo detector laser power control
Direct interface with PSI-0204-11 modulator bias controller for externally modulated systems
Direct interface with modulator output optical power monitor
Adjustable optical power output
Status indicators for laser, power and fault
Available with 40 mw 1550nm laser factory installed

Beyond standard specifications, PSI can modify the PSI-2600-11 to meet the exact requirements of your application. Common
modifications are adaptations for laser pin configuration or compliance with custom physical dimensions. Please contact PSI
