The EXALOS GaAs/GaN material system
EXALOS has a long experience creating industry-leading light sources:
- 20+ years with InP devices
- 15+ years with Gallium Arsenid (GaAS) devices
- 10+ years with Gallium Nitrid (GaN) devices
Thanks to the advanced GaAS/GaN material system, today EXALOS is the only company that provides RGB SLEDs.
Advanced Red SLEDs, including in the highly challenging, lower red spectral range 635 nm.
The world´s first Blue & Violet SLEDs.
The world´s first Green SLED.
EXALOS SLEDs are designed as reliable high-performance light sources with a long life span. Stable electrical characteristics during the whole lifetime are one of the most essential features for the acceptance of demanding products for OCT, Current Sensing or See & Aerospace navigation systems.
Long Lifetime for High Performance RGB SLEDs
In 2016 EXALOS has already demonstrated the reliability of GaN-based SLEDs emitting at 405 nm. A special optimized design reached an estimated lifetime of over 5000 hours under real-life test conditions. Furthermore, the use of optimized p-doped layers allow maximum output powers as high as 350 mW for an injection current of 500 mA have been achieved in continuous-wave operation at room temperature. The test details were scientifically published:
