The Single-Channel Superluminescent Diode Source from DAYY Photonics combines advanced superluminescent diode technology with an integrated spectral platform to deliver a versatile, reliable, and easy-to-integrate photonic light source for research, industrial, and medical use.

At the heart of this source is a superluminescent diode (SLED) - a semiconductor light emitter that bridges the gap between laser diodes and LEDs by producing high-brightness light with a broad spectral output and low temporal coherence. This makes SLED sources ideal for applications where broad wavelength coverage and minimal interference effects are critical, such as optical coherence tomography (OCT), optical sensing, telecom test equipment, and advanced imaging systems.

What does “superluminescent diode” mean?

It’s a semiconductor light source that combines high brightness with a broad spectrum, similar to a laser diode but with low coherence. Useful where a wide, smooth spectrum is required.

What wavelengths are available?

Models cover multiple centre wavelengths from ~770 nm up to ~1680 nm.

Can I control output power and monitoring?

Yes - models offer precise power control from 0 % to 100 % and some include a monitor photodiode.

Is there low polarization output?

Low degree of polarization (DOP) output options (<5 %) are available to minimize polarization effects in sensing systems.

What makes this different from a laser?

Unlike a laser, a SLED produces broadband, low-coherence light - better for high-resolution imaging and interferometric measurement with reduced speckle.
