HIGH BANDWIDTH DFB LASERS-AA0701 SERIES
7-pin k-package
The AA0701 distributed feedback laser (DFB) is an InGaAsP/InP multi-quantum well laser diode.
The module is ideal in applications where high bandwidth, mode stability, low relative intensity noise (RIN) and stable output power are needed.
AA0701 contains a thermo-electric cooler, thermistor, back facet monitor detector, and bias tee.
The module is designed and built using Gooch & Housego’s high-reliability platform for defense components.
