Superluminescent Diode (SLD) modules

All standard products

Description

Superluminescent Diodes (SLDs) are used in various applications requiring high-power, spatially-coherent, wide-spectrum light sources. The unique characteristic of superluminescent diodes is that they combine the features of laser diodes – such as high spatial coherence and high brightness – with the very wide spectrum inherent to light-emitting diodes. The output emission is the amplified spontaneous emission of laser diode epi-structures in which lasing is suppressed by special measures.

These are light sources of choice for many disruptive technologies: optical coherence tomography, low-coherence interferometry, distributed Bragg grating sensing, speckle-free illumination and many others. The module design is Telcordia GR-468-CORE qualified.

This document describes the performance of standard products containing a single Superluminescent Diode (SLD) module:
