Combined SLED Modules (EXC)

Combined SLED Modules (EXC)

The EXALOS combined-SLED modules are high-performance fiber-coupled light sources based on superluminescent light emitting diodes (SLEDs).

For the first time, multiple SLED chips are integrated into a standard 14-pin Butterfly package to provide an ultra-wideband optical spectrum.
All beams are combined with free-space optics, aligned in polarization, and coupled into a single-mode output fiber using high-precision alignment technology.

The Combi-SLEDs can be customized to meet the highest performance demands. At the same time, the system integration is easy thanks to the Combi-SLEDs being offered in a standard 14-pin Butterfly package with fiber output. EXALOS is also offering a Driver Board (EBD10200) that provides ultra-stable performance from any of our Combi-SLEDs mounted on this board.
