1.53µm PM - Planar Glass Laser series

Preliminary:

The PM-PGL laser module is based on the DFB planar erbium-doped-glass technology. It presents a single frequency operation above 1.53µm wavelength, at the output of a PM single-mode fibre. Its key features are a very narrow line-width of 10kHz, and a low noise signal with a RIN below -140dB/Hz, for 10mW of CW output power.

It is designed for application requiring high wavelength stability and low noise, together with single spatial and single longitudinal mode, as well as fibre delivery in a compact environment.

The PGL laser module is manufactured using Teem’s proprietary glass waveguide technology and complies to Telcordia GR 1312 industry standards for reliability, performance and robustness.
