Distributed feedback lasers – DFB & DBR
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 quantum well (QW) or InAs/GaAs quantum dot (QD) active region and proprietary chip design.
As of today, DFB laser and DBR laser are two of the most commonly utilized laser variants, especially regarding usage in scientific research and operations. Both laser variants operate with one singular longitudional mode, they are also exceptionally reliable regarding efficiency, spectral purity and long-time performance in various applications.
