Product Overview:

Semiconductor Optical Amplifier Controller Overview

These pulse drivers for laser diodes are optimized for controlling semiconductor optical amplifiers, supplying the drive current, the TEC controller, and the butterfly mounting pads. These 1.2 amp output current modules are designed to fully control a butterfly packaged fiber-coupled SOA. These driver and control modules operate as trans-conductance amplifiers with an input DC voltage and a scaling current output. These units from Analog Modules include a TEC controller to precisely stabilize the temperature of the module; a heatsink is required to dissipate the waste heat from the TEC inside the butterfly package.

Pulse Driver Protection Features:
These modules include an adjustable current limit to protect the diode from over-current damage. Also, the driver is automatically disabled when the laser diode temperature exceeds the TEC controller set-point by ±1˚C. The pulse driver current is disabled when the laser current field effect transistors which control the bias current have a junction temperature which exceeds 125˚C. These modules include all required cables.
