Superluminiscent Light Emitting Diodes

Ofls B

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 and low temporal coherence typical of LEDs, with high output power levels and high spatial coherence typical of se- miconductor 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.

Optical sources are provided in two various packaging according to their cooling. Cooled version inclu- des TEC (thermo electrical cooler) inside to stabilize SLEDs temperature.
In addition to standard products, SAFIBRA can also offer devices with custom performance and cus- tom housing/ solutions. Our diverse portfolio of SLEDs provides our customers with a wide variety of choices, when determining the optimal SLED for their application.

Optical source can be controlled via front panel buttons or USB interface. The SW user friendly inter- face enables to control and monitor light source parameters.

The OFLS-B series are universal optical light sources optimal for fiber optic sensor applications, tele- communication, instrumentation, fiber optic gyroscopes and medical imaging applications.

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