DeepLight signed the contract on the Early Technology Development “Narrow linewidth frequency agile integrated photonic lasers for space” (IDEA: I-2021-03417).

ESA’s Open Space Innovation Platform (OSIP) seeks novel ideas for new space research activities. Campaigns and Channels invite solutions to specific problems or ideas on more general topics, with those run by Discovery & Preparation, including the Open Discovery Ideas Channel, specifically looking for ideas that could be implemented as system studies, early technology developments, or PhD or postdoc research co-funded by ESA and a university.

DeepLight aims at establishing a new class of wafer-compatible and cost-effective integrated lasers that can address the entire wavelength range from the blue (400 nm) to the infrared (2.7 µm). The ultra-compact devices will offer unprecedented performance in terms of ultra-narrow linewidth (sub-kHz) with exceptional frequency agility across the electromagnetic spectrum. Within this project, we will build a device operating at 1550 nm with >10 mW output power for FMCW LiDAR. We will build a laser prototype at 422 nm for Sr+ transition (for laser cooling and qubit construction) with 1-5 mW output power and a high power prototype (aiming at >100 mW) at 461 nm for optical lattice clocks (Sr transition).
