780-1330nm DFB & DBR lasers
Distributed Feedback (DFB) and Distributed Bragg Reflector (DBR) laser diodes are the light sources emitting extremely narrow spectral line with bandwidth below 5MHz and typical Side Mode Suppression Ratio (SMSR) > 40dB.

Innolume’s GaAs-based DFB and DBR lasers cover 970-1330nm spectral range by utilizing of InGaAs QW or InAs/GaAs QD active region and proprietary chip design.

3 - All the wavelength of below ranges are available with 1nm step. 90% Chips on stock!

4 - means we provide such the DFB that can be temperature tuned to exact nominal wavelength in 15-35C range.


Modules with a built-in Optical Isolator are available by request.
