High-power External-cavity Laser Modulator for Integrated Transmitters (HELMIT)

Press Release

Press Release

Physical Sciences Inc. (PSI) has been awarded a contract from the U.S. Space Force to develop a low-cost packaged laser transmitter capable of Watt-scale output powers and modulation bandwidths with up to 100 GHz.

On-chip high-power and high-bandwidth laser transmitters can be a cost-effective solution to the problem of equipping our distributed national defense network with the hardware needed for secure communications. The large size, weight, power and cost (SWaP-C) of portable laser communication systems has greatly limited the proliferation of laser communication technologies in the field. To overcome this challenge, Physical Sciences, Inc. (PSI) will develop a packaged high-power, high-bandwidth laser transmitter based on integrated photonics. To achieve this performance at the lowest SWaP-C, PSI’s High-power External-cavity Laser Modulator for Integrated Transmitter (HELMIT) platform will combine an external cavity laser capable of producing Watt-scale output powers with an on-chip electro-optic modulator capable of 100 GHz bandwidths.
