Description
NASA Langley Research Center in Hampton, VA solicits interest from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use.
THE TECHNOLOGY:
NASA Langley Research Center has developed a new technology for measuring the junction temperature of laser diode arrays (LDAs) that can support dramatically improved LDA fault analysis and lifetime estimates. Laser diode systems contain a driver that provides nominal quasi-continuous wave pulses. In this technique, a second driver is used to provide precise pulses between operational pulses. This facilitates the accurate derivation of junction temperatures by precisely measuring the voltage of these second pulses. Furthermore, this technique uses small injections of current, and resultantly does not contribute to any heat cycling issues within the LDA.
The technology provides better spatial and temporal resolution than spectral chirp or thermal imaging methods and can be integrated into existing LDA systems, such as laser diode drivers, without significant additional costs (including weight, power, and space). Potential applications include quality control and screening of LDAs for maximum lifetime, optimizing development of operational parameters, or providing real-time operational diagnostics/prognostics.
To express interest in this opportunity, please respond to Sean Sullivan, Research Triangle International (RTI), at: NASA Langley Research Center, Strategic Relationships Office (SRSO), 17 West Taylor St., Mail Stop 218, Building 1212, Room 110 Hampton, Virginia, E-mail: Sean.D.Sullivan@NASA.gov, or phone: 757-864-5055. Please indicate the date and title of the FBO notice and include your company and contact information.
RTI is responsible for aggregating and acknowledging all responses. These responses are provided to members of NASA Langley’s Innovative Partnerships Office within the SRO for the purpose of promoting public awareness of our technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities. If direct licensing interest results from this posting, SRO will follow the formal licensing process of posting in the Federal Register as required. No follow-on procurement is expected to result from responses to this Notice.
