Parameter extraction for dfb laser diodes
WebA DFB laser is typically defined as one where the internal grating is actively pumped (is located in a region which provides optical gain) and is uniformly distributed between both output facets in an edge emitter. The grating may be passive (refractive index gratings), or active (gain or loss gratings).
