Blue SLED

Exlaos 425nm Superluminescent Light Emitting Diode (SLED). Superluminescent Emitting Diodes (SLEDs) are semiconductor devices that emit broadband light through electrical current injection. SLEDs are a hybrid between LEDs, which emit broadband light in all directions, and semiconductor laser diodes, which emit narrowband light with a well-defined laser beam. In this sense, SLEDs can be understood as broadband laser diodes with a beam-like output.

Broadband means that SLEDs emit an optical spectrum that is broad in the wavelength or frequency domain. The spatial domain is correlated to the frequency domain through the Fourier transform. A light source that is broadband in the frequency domain is therefore narrowband in the spatial domain, meaning it is having a short coherence length. In this sense, SLEDs can be understood as incoherent laser diodes.
