DATASHEET| MARCH 16, 2008 1792 ECCW Narrow Linewidth CW External Cavity Laser Diode The 1792 ECCW series external cavity laser is a cost effective solution for a coherent laser source. The laser is fabricated in a 14-pin hermetically sealed butterfly package that incorporates a bias tee circuit, an integrated thermoelectric cooler (TEC), a thermistor, and a Features Narrow linewidth, < 10 kHz available back facet monitor photodiode. The 1792 ECCW provides substantially lower phase noise and a longer coherence length than other semiconductor lasers, including DFB lasers. The wavelength stability is ITU wavelengths across the Cband assured by design, eliminating the need for wavelength lockers and 100 GHz channel spacing complex feedback control circuits. 10 mW minimum output power Industry standard, high reliability, hermetic 14-pin butterfly package Performance Highlights Min Typical Minimum Optical Output Power, Version A 15 20 Version B 10 12 Optical Linewidth, CW, Version A - - 10 Version B - 25 50 -10 - +65 C 1527 - 1570 nm Optical Isolation 35 - - dB Optical Return Loss 40 - - dB Lidar Side Mode Suppression Ratio, CW 40 - - dB Optical test and instrumentation Relative Intensity Noise - -155 - dB/Hz Excellent long-term wavelength stability eliminates the need for a wavelength locker Back-facet monitor Designed to meet Telcordia GR-468 qualification standard Applications Seismic sensor applications Operating Case Temperature Range Center Wavelength (100 GHz ITU Grid) Max Units - mW kHz Interferometry Spectroscopy Microwave photonics See following pages for complete specifications and conditions.

Handling and Mounting 1. The Laser should be mounted on a heat sink at least 13 x 35 mm in size with surface finish better than 1 m and flatness better than 25m. It is recommended that the laser be mechanically mounted to the heat sink using M2-3 mm (#2-56) screws. Apply torque 0.1-0.11 m*N (0.8-1 lb*in). It is also recommended to use thermally conductive grease between the laser package and heat sink. 2. The fiber pigtail must not be subject to a bend radius below 35mm.The fiber is unable to withstand temperatures in excess of 120 C without degradation. Avoid high temperature contact during soldering EMCORE CORPORATION 6 1792 ECCW Narrow Linewidth CW External Cavity Laser Diode DATASHEET| MARCH 16, 2008 Laser Safety Class IIIb Laser Product This product meets the appropriate standard in Title 21 of the Code of Federal Regulations (CFR).
