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

Key Characteristics• C-band (1537-1565 nm)
and 1310 nm wavelengths• 10 or 18 mW ex-fiber output power options
Features• 10 or 18 mW output power• High bandwidth• Built in isolator• Ultrafast pulsing capability• Laser welded, hermetically sealed• Built in TEC, thermistor, and monitor detector• Rugged to shock and vibration
Applications• Analog RF links• High speed pulsing
