Frequently Asked Questions

What is the DAYY Photonics OSE2 Multi-SLED broadband light source?
The DAYY Photonics OSE2 Multi-SLED is a compact near-infrared broadband superluminescent diode light source packaged in a 32-pin butterfly module. It integrates 2 to 6 SLED emitters, independent monitor photodiodes, a common thermoelectric cooler, an integrated optical isolator, and spectral stitching technology to deliver broad, stable optical output for OCT, optical sensing, telecom testing, and component characterization.
What wavelength range does the OSE2 Multi-SLED cover?
The OSE2 can be configured with SLEDs ranging from 770 nm to 1680 nm. Depending on the selected diode combination, it can provide overlapping near-infrared spectral coverage tailored to specific applications such as biomedical OCT, industrial OCT, optical metrology, and telecom test systems.
How much optical output power is available from the OSE2 Multi-SLED?
The OSE2 provides fiber-coupled output power from 10 mW to 40 mW, depending on configuration. For applications that do not require fiber coupling, free-space versions are available with higher output power from 30 mW to 130 mW and a collimated beam output.
What bandwidth can the OSE2 Multi-SLED light source provide?
The OSE2 supports FWHM bandwidths from 40 nm up to 460 nm, depending on the selected SLED channels and spectral stitching configuration. This broad bandwidth is especially useful for optical coherence tomography and other low-coherence interferometry applications requiring high axial resolution.
How does spectral stitching work in a Multi-SLED source?
Spectral stitching combines the output of multiple SLEDs with different center wavelengths into a single spatially coherent beam. In the OSE2, overlapping spectra are designed to produce broader near-infrared coverage while maintaining low temporal coherence, stable power, and application-specific spectral shaping.
Why are monitor photodiodes and a TEC important in this SLED light source?
Each SLED in the OSE2 includes an independent monitor photodiode, allowing better optical power monitoring and control for each channel. A common thermoelectric cooler helps stabilize the operating temperature of the SLEDs, improving center-wavelength stability, output power consistency, and long-term optical performance.
What output coupling options are available for the OSE2 Multi-SLED?
The standard light output is fiber-coupled with an FC/APC connector, with optional FC/PC or SMA connector configurations. Free-space models are also available for applications requiring a collimated beam and higher output power instead of fiber optic coupling.
