Milestone demonstrates inherent reliability of Daylight's QCL technology, says the US firm.
SAN DIEGO--(BUSINESS WIRE)--Daylight Solutions, Inc. (www.daylightsolutions.com) announced today the company has reached two major milestones as part of its ongoing reliability characterization and growth program for quantum cascade laser (QCL) technology. Over 1 million hours of QCL device operation, and over 250,000 hours of fully packaged QCL module operation have been accumulated as part of this program. All units under test were sampled from high-yield, commercial production. The units maintained optical power levels above specifications throughout the test, and continue to operate without failure.
Over eighty (80) individual QCLs sampled from five different epitaxial wafers are being evaluated as part of the current reliability characterization program. Lasers are running in both continuous-wave (CW) and pulsed (quasi-CW) modes of operation to explore the reliability effects of each operating condition.
While some of the devices are operating at standard room temperature, the majority of the tests are being conducted with the QCL devices running at a higher temperature of 60 degrees Celsius. Elevating the device operating temperature has been demonstrated to accelerate the aging effects of standard group III-V semiconductor diode lasers, and creates an added stress component for these tests.
In practice, the thermal management system of the QCL-based products will maintain device temperatures around 25 degrees Celsius while allowing the ambient temperature to increase beyond 71 degrees Celsius while maintaining performance.
“The achievement of this milestone demonstrates the inherent reliability of our QCL technology,” said Dr. Timothy Day, CEO for Daylight Solutions. “Our team is committed to the continuous execution of reliability growth programs to support the demanding requirements of our customers.”
Daylight Solutions and its wholly owned subsidiary Daylight Defense, LLC, continue to integrate their QCL “light engines” into a variety of products that serve commercial and defense markets. The company’s modular design approach allows for new capabilities to be transitioned into new products rapidly, reducing the cycle-time from design to deployment.
