EXALOS expands into micro-LEDs for direct projection displays

EXALOS of Zurich, Switzerland, which designs and manufactures light sources based on superluminescent light-emitting diodes (SLEDs) and external-cavity tunable lasers for optical coherence tomography and fiber gyroscopes, has developed new methods of growing crystals for producing micro-light emitting diodes (LED), providing more efficient means of realizing light sources for direct projection displays, including for augmented reality (AR) and virtual reality (VR) applications.

The epitaxial growth technology was developed in collaboration with the Swiss Federal Institute of Technology in Lausanne, and leverages patent-pending methods of producing vertical emitters with what are claimed to be unprecedented robustness and performance.

Currently, EXALOS has produced devices with emission in the short-wavelength region for blue-violet micro-LEDs. The firm says that the design could be easily transferred to other emission wavelengths such that RGB light emission designs could be envisaged. 

"For the next generation of display, micro-LEDs will be a critical component for efficiency and brightness, and EXALOS has now developed methods for creating micro-LEDs that have the performance and the features required for a wide range of applications, particularly in AR and VR," says CEO Dr Christian Velez. "We are ready to seek out partners for bringing new display products to market."

EXALOS is detailing its micro-LED solutions in booth #430 at the SPIE Photonic West 2016 exhibition in San Francisco (16-18 February).
