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.
