Broadband light sources

Broadband light sources

Safibra's SLEDs (Superluminiscent Light Emitting Diodes) are of Light Emitting Diodes (semiconductor light sources that merge the best features LEDs and semiconductor lasers. The SLEDs provide broadband output optical spectrum (quite different againts supercontinuum lasers)and low temporal coherence typical of LEDs, with high output power levels and high spatial coherence typical of semiconductor lasers.

SAFIBRA offers a wide range of standard SLED sources with different wavelengths ranging from 650 to 1600 nm, with different power and bandwidth values according to customer's need.

Particularly the light source could be applied in research field, where experiments under specific conditions are performed. Thanks competitive pricing is also suitable for teaching and learning purposes especially in fiber optics and optoelectronics labs at university institutions.

In addition to standard products, SAFIBRA can also customize optical light sources according customer's needs like dual OFLS-B .
