A compact RGB LD module – a light source for AR displays (July 2021)

EXALOS presents a miniaturized, full-color RGB light source module for near-to-eye display systems, incorporating three semiconductor laser diodes (LDs) that are integrated on a free-space, micro-optical bench together with collimation optics and wavelength filters. The ultra-compact package delivers up to 10 mW per color at low power dissipation values of 640 mW and provides low-divergent output beams.

Highly Efficient RED SLEDs at 625-650 nm

Highly Efficient RED SLEDs at 625-650 nm

Superluminescent light-emitting diodes (SLEDs) are very attractive as compact, highly efficient light sources for various applications in the visible red spectral region. EXALOS investigated the electro-optical performance of SLEDs operating at center wavelengths of 625-650 nm with interesting results.

Superluminescent LEDs enter the Mainstream

Superluminescent LEDs enter the Mainstream

SLEDs, also known as high-power LEDs and “laser diodes operating below threshold,” are semiconductor light sources that have a broadband output optical spectrum, like LEDs, at high power levels, like laser diodes. This combination is valuable in a variety of applications, and as a consequence, these emitters are finding commercial use.
