SLED-Based Broadband Near-Infrared Source

Photonics & Imaging Technology INSIDER

Avo Photonics (Horsham, PA) design, development, and manufacturing, was commissioned by Luxmux Technology Corporation, to develop and manufacture a solid-state, broadband, continuous emitter for use with their line of miniature integrated spectrometers. The emitter combines the outputs of multiple super-luminescent LEDs (SLEDs) into a polarization-maintaining single-mode fiber. Such an accomplishment required collimating multiple beams and achieving collinearity to an overlap of 700 um and pointing to within 250 urad. The result is a >100 mw, fiber-coupled source with continuous emission over the 1250 – 1750 nm band.
