1260-1360nm DFB Laser Diode

Distributed feedback (DFB) and distributed Bragg reflector (DBR) laser diodes are light sources emitting an extremely narrow spectral line with a bandwidth below 5 MHz and typical side mode suppression ratio (SMSR) > 40 dB.GaAs-based DFB and DBR lasers utilize InGaAs quantum well (QW) or InAs/GaAs quantum dot (QD) active regions and proprietary chip designs, covering the spectral range from 970 nm to 1330 nm.To date, DFB and DBR lasers are common laser variants, especially for use in scientific research and operations.Both laser types operate in a single longitudinal mode and are highly reliable in terms of efficiency, spectral purity, and long-term performance across various applications.
