DAYY’s Multi‐SLED® (superluminescent diode) OSE2 is a compact broadband light source that operates in the near‐infrared region. The product itself is a 32‐pin butterfly package that uses a set of superluminescent diodes, one monitor diode for each SLED (enabling better power control and monitoring capabilities), a thermoelectric cooler (TEC), an integrated isolator, and a spectral stitching design to provide overlapping spectral coverage. The Multi‐SLED can be configured with up to six light sources.

The OSE2 includes various spectral coverages with SLED’s ranging from 770nm to 1680nm, with up to 40mW of optical power. This product enables stable power and center‐wavelength performance over time, and steady optical performance over a wide spectrum of wavelengths. The OSE2 is compact and easy to use, making it an appropriate fit for many different types of manufactured assemblies requiring light power.

The Multi‐SLED uses DAYY’s technology of spectral stitching to provide extensive spectral coverage. This technology intergrates
multiple wavelengths into a single spatially coherent beam with low temporal coherence and broad spectral coverage. The
Multi‐SLED product lines can be spectrally tailored to suit specific application needs.
