Photonics West is the world’s largest optics and photonics event, bringing together thousands of innovators in optics, lasers, and quantum technologies at the Moscone Center in San Francisco, CA . This global stage is where cutting-edge research meets real-world applications. indie will be exhibiting at all three SPIE exhibitions, including Bios (booth #8357), Photonics West (booth #4719), and Quantum West (booth #510), along with five technical presentations covering our optical, laser, and SLED solutions. Presentations: Compact optical module with RGB superluminescent diodes and collinearly aligned collimated output beams Uncooled micro-RGB optical module with wavelength-stable DFB/DBR laser diodes and collimated output beams High-performance GaN DFB lasers from 400 nm to 520 nm Coherent sensing transceiver based on narrow linewidth semiconductor laser and silicon photonics IQ receiver Read through the sneak preview and be sure to join us at one, two, or all our technical presentations! Compact optical module with RGB superluminescent diodes and collinearly aligned collimated output beams When : 19 January 2026 • 5:30 PM – 7:00 PM PST We demonstrate a new miniaturized, full-color RGB light source module on a micro-optical bench architecture with a collimated beam output for near-to-eye display systems, incorporating semiconductor superluminescent diodes (SLEDs) for red, green and blue emission. All SLED emitters are generating large optical peak power levels of 350 mW per color with short electrical current pulses at short duty cycles, thereby massively reducing the average power consumption. This new uncooled RGB SLED light source module has a SMD-mountable ceramic package for direct reflow soldering onto printed circuit boards and delivers collimated beams having a high circularization of better than 85% with large 1/e2 beam diameters around 1.0 mm that are collinearly aligned with low angular alignment errors.

A multi-layer, SMD-mountable ceramic acts as a heatsink but also as an optical bench for the light sources and the free-space collimation optics to deliver a collimated, circular output beam. The DBR/DFB laser sources deliver output power levels of more than 50 mW per color over a wide temperature range with a temperature-related wavelength shift that is 3-4-times smaller compared to conventional RGB Fabry-Perot laser diodes. Therefore, this will be beneficial for AR/MR display systems based on holographic grating structures that show a significant change of diffraction angle and efficiency with wavelength.

These devices employ monolithic gratings integrated into single-transverse-mode ridge-waveguide structures, achieving high side-mode suppression ratios and stable operation over a wide current range. They exhibit low threshold currents, high differential efficiencies and wall-plug efficiencies comparable to Fabry–Perot lasers. Wavelength tuning
