Matthew Welch (G&H) presented the talk titled: “High power WDM sources for laser communication” at 2022 SPIE Photonics West conference, Event SPIE LASE, in San Francisco California.
Paper abstract:
The next generation high bandwidth optical links from earth to space will requirement the development of new high power WDM sources. In this paper G&H present the latest results of their ongoing development of these sources. Namely the development and testing of a 50W optical fibre amplifier that operables across much of C-band is presented as well as a high power wavelength division multiplexer, designed to combine multiple high power amplifiers outputs into a diffraction limited beam.
