High Power (50W) WDM Space Lasercom 1.5um Fiber Laser Transmitter, Phase I

Metadata Updated: November 12, 2020

Fibertek proposes to develop and demonstrate a spaceflight prototype of a wideband, high power (up to 50W), polarization maintaining (PM), 1.5-um fiber laser transmitter, supporting high data rate wavelength-division-multiplexed (WDM) operation for space optical communication links. The proposed 1.5-um fiber laser transmitter will support up to 8x WDM channels at 4W/channel, with 256-ary pulse-position-modulation (PPM) format, operating at ~10-kW peak power per channel, with >20-nm gain-flat bandwidth, and with 20% power conversion efficiency. The proposed 1.5-um fiber laser transmitter also supports 20x WDM channels at 2.5W/channel, operating at 10 GHz data rate (for 200GHz total) in burst-mode RZ-DPSK modulation. The proposed 10x scaling of the average and peak power performance for such a space-qualifiable WDM 1.5-um transmitter enables >100x data-rate scaling of current space laser communication links. The successful outcome of Phase I and II will be to develop a prototype, space-qualifiable, high-efficiency, high-power (50W), 1.5-um WDM space lasercom transmitter. This advances the Technology Readiness Level (TRL) from 3 to 5 and supports TRL-6 environmental testing in subsequent phases.
