Product Overview:

Pre-Configured 1491nm DFB Source and CW Control Module

These CW 1471nm DFB single-frequency laser source & control modules offer the user a pre-configured, calibrated bench top source solution. The integrated 1491 nm laser diode source module is single frequency and single-mode fiber coupled. Both the chip in the butterfly package and the package itself were designed and optimized to provide excellent long term reliability. The coupling of the laser light into the fiber is based on proprietary techniques and manufacturing processes that provide high peak output power.

High Reliability Telcordia GR-468 Core Compliant Laser Source

The butterfly laser package is coupled with SM fiber, with an FC/APC connector. The source is rated for up to 10 mW output power in continuous wave mode (CW), and the controller accepts external modulation. The internal thermoelectric cooler (TEC) and thermistor are accurately controlled by the CCS-CW source electronics, and keep the laser at a safe operating temperature. The back-facet monitoring photodiode allows for constant-power control of the light source output. All of these integrated elements can be controlled and monitored through the control electronics module.

Laser Diode Control Electronics and Butterfly Mounting Module

The control electronics and mounting module for these laser diodes delivers high stability bias current, a precision TEC controller and a pre-configured ZIF mounting socket. These control modules provide multiple mechanical, thermal, and electronic protection features to protect the laser diode and ensure long operating lifetime. The TEC controller incorporates a fast-feedback PID control loop to provide high temperature set-point stability, which also helps to maintain a stable wavelength. The temperature limit keeps the source from thermal damage, and can be adjusted via the graphical user interface. Additionally, multiple bias current / voltage protection features are designed to keep the source safe from ESD, power outages and reverse voltage. A user controlled current limit clamps the current at the set limit level.

USB and Control Software

The user can set and monitor all of the control parameters of the DFB source laser using the USB input and the supplied GUI software. These units ship with the USB cable to connect your PC to the connector on the side panel. A simple to use single page graphical user interface allows you to control all of the CW parameters as well as set current and temperature limits. Other features of these control modules include a daisy chain output to control multiple systems simultaneously, sync output, alarm monitor, and back facet diode monitor to measure and control the DFB laser's power.
