DFB Butterfly Laser: Performance Testing Technology
Working Principle of DFB Butterfly Laser The DFB (Distributed Feedback) butterfly laser operates on the principle that when current is injected into the active region, electrons and holes recombine to emit photons. These photons are reflected within the grating structure on the surface of the active layer, triggering stimulated emission. Through selective feedback and amplification […]
