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.
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.
