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.
