Product Overview

NeoPhotonics’ family of high power, single mode edge-emitting CW laser diodes covers four wavelengths on the CWDM spacing over O-band – 1271 nm, 1291nm, 1311 nm and 1331 nm – for Silicon Photonics applications. With a buried heterostructure (BH), multiquantum well (MQW) active core, and a distributed feedback (DFB) grating layer, these lasers provide a typical facet power of 30mW at 75C.

In addition to the DFB laser itself, two additional configurations are available:
– DFB laser with an integrated mode-converter (spot-size converter) for optimized optical coupling into a Silicon Photonics modulator; and
– DFB laser with an integrated mode-converter and precision reference surfaces for flip-chip passive alignment.
