Ultra-Coherent Semiconductor Laser Technology

In this STTR program, technology created at the University of California at Santa Barbara (UCSB) to fabricate silicon photonics based integrated laser devices, including wafer bonded gain elements, will be utilized to develop ultra-coherent integrated laser devices that are widely tunable. Novel laser designs developed by Morton Photonics, taking advantage of ultra-low loss microresonator based filters / reflectors, and benefiting from slow light effects, will be fabricated using the novel silicon photonics platform developed by UCSB. These integrated lasers will provide an ultra-coherent output, also with ultra-low relative intensity noise (RIN), and be fully tunable across the 1530nm to 1565nm wavelength range. The laser product developed through this program will take advantage of CMOS foundries and the tremendous cost and scaling advantages of silicon processing technology, leading to a high volume low cost product.
