LONGWAVE PHOTONICS LLC — National Aeronautics and Space Administration SBIR Phase I: S1
LONGWAVE PHOTONICS LLC — SBIR Phase I award from National Aeronautics and Space Administration.
Phase I SBIR feasibility signal
- Phase I awards fund proof-of-concept work. For capture teams, they mark early interest from National Aeronautics and Space Administration in a technical approach.
- Watch for Phase II follow-ons from the same firm/topic family — that conversion path is where budgets and transition pressure rise.
- Obligated amount $125,000. Cross-check similar awards in the same agency and technology tags for going-rate context.
- Topic code S1 links this award to a solicitation family — search the same topic stem for incumbents and recompete timing.

Description
LongWave Photonics is proposing a novel DFB Quantum Cascade Lasernbsp;(QCL)nbsp;based on active cryogenic alignment of a grating to the gain chip, in ordernbsp;to achieve accurate frequency output (e.g. 4.744 THz).nbsp; Devices will be based on waveguides with loosely confined optical modes, resulting in highly symmetric output beams, and higher output power levels.nbsp; The devices will be suitable for use as either local oscillators, or as frequency references for spectrometers.nbsp; The second thrust of this proposal is in improving the frequency stabilization the QCLs.nbsp; LongWave is proposingnbsp;a robust optical frequency stabilization technique based on difference frequency generation of the THz QCL and a NIR pump wavelength.nbsp; The resulting QCL will be stabilized to lt;20 kHz linewidth, and will be capable of simultaneously stabilized several QCLs in the 2 to 5 THz frequency range.nbsp;nbsp;
