The EXALOS combined-SLED modules are high-performance fiber-coupled light sources based on superluminescent light emitting diodes (SLEDs).
For the first time, a combination of two or three SLEDs are integrated into a standard 14-pin butterfly package. 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-SLED products are highly customizable and meet highest performance demands. At the same time, the system integration is easy thanks to the standard package and fiber output. EXALOS is also offering drive electronics to provide ultra-stable SLED current operation, temperature control and monitor signal output.

Our product specifications can be accessed from the links in the table below.
The combi-SLED module EXC250002 offers a 10-dB bandwidth of ~160 nm at a center wavelength near 845 nm with ~11 mW of optical output power and a coherence length of ~3.0 μm (in air).
The combi-SLED EXS250003 offers a lower 10-dB bandwidth of ~120 nm with a coherence length of ~4.3 μm (in air). Other combi-SLED modules can be realized upon request. EXALOS can offer SLEDs (or LDs) over a wide spectral range from the near-UV (390 nm) to the near-IR (1700 nm).
* The products are still under development. Specifications are preliminary.
