Superluminescent diode

The best recognized and the most often used solid-state light emitters so far are light-emitting diodes (LED) and laser diodes (LD), that could be applied in a wide array of industries due to their versatile optical properties. However, some optoelectronic devices, such as fiber optic gyroscopes or optical coherence scanners, have to operate in high spatial light coherence and low time coherence.
These requirements are fulfilled by superluminescent diodes (SLD), combining the advantages of LED and LD solutions

Our technology enables to produce a diode featuring improved optical parameters as compared to the ones currently available on the market. The diode is characterized by optical power increased up to 200 mW, improved light emission efficiency 1W/A and low time coherence. Those properties guarantee superior image quality, smoother emission spectrum and higher light extraction from the device. Due to the reduction of the number of technological processes needed to produce a final product, this technology is cheaper as compared to existing solutions.

The suggested solution may be applied as a visible light source in the following industries: optoelectronics, photonics, fiber optic telecommunications, projection techniques, fluorescent microscopy or optical coherence tomography.

The offer comprises the technology based on manufacturing of superluminescent diodes emitting blue-violet electromagnetic radiation of increased level surface roughness, due to the application of a special antireflective coating.
