Ultra-narrow butterfly laser diode module

Elliot Scientific has announced that it is now offering the Eblana Photonics EP1550-NLW-B Butterfly Laser Diode Module to specifiers in the coherent communications, sensors, medical device and imaging equipment industry sectors.

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.
