Wavelength stable uncooled fibre grating semiconductor laser for use in an all optical WDM access network
Robert Campbell,J.R. Armitage,G. Sherlock,D.L. Williams,R. Payne,M.J. Robertson,Richard Wyatt +6 more
TL;DR: In this article, the use of angled facet semiconductor laser chips in fiber grating laser (FGL) is shown to dramatically improve device characteristics over conventional normal facet FGLs, allowing the laser to operate with no temperature control at 155 Mbit/s and makes it feasible for it to be used as a wavelength stable, uncooled source in a WDM optical access network.
