Superluminescent diodes at Inphenix Inc https://www.inphenix.com/en/superluminescent-diode-devices/ #Superluminescentdiode (SLDs) is an edge-emitting semiconductor light source. SLDs are similar in geometry to lasers but have no built-in optical feedback mechanism required by LDs for stimulated emission to achieve lasing. #Superluminescentdiodes are applied in situations where a smooth and broadband optical spectrum, combined with high spatial coherence and relatively high intensity.
