The product is already in use for high bandwidth coherent communications applications where, for example, high spectral efficiency, phase encoded signals are used to overcome transmission bottlenecks.

The EP1550-NLW-B Series lasers have a guaranteed emission line-width specified at 400 kHz and below, with highly linear Light Current characteristics and high Side Mode Suppression Ratio (SMSR).

A strained multi-quantum well Discrete Mode laser diode chip is supplied in an industry standard hermetically sealed 14-pin butterfly integrated with optical isolator, thermo-electric cooler (TEC), thermistor and power monitor photodiode. Each device is shipped with individual test data of the measured linewidth.

Features
o Narrow Linewidth (typically 350 kHz)
o Excellent wavelength control and stability
o Industry Standard 14-pin Butterfly package
o High SMSR performance
o Typically 6 mW output power

Applications
o Optical Sensing
o Lidar
o Coherent communications
o Interferometery
o Test and Measurement
