  • SLD light sources

Overview

An SLD light source emits low-coherence light with a broadband spectrum like LED and high brightness like LD. Light emitted from a narrow active layer like LD effectively couple to the fiber. SLD light source can be used for optical measurements and sensors, including fiber optic gyroscopes and OCT.

FiberLabs provides highly stable fiber-output SLD light sources in different wavelength bands from visible to near-infrared wavelengths. Our standard lineup includes bench-top type convenient for experiments and module type for OEM integration.
