AZURi's 1550nm Super Luminescent Diode (SLD), designed with unique quantum-well structures. It is an edge-emitting semiconductor light source based on the ridge waveguide on N-type substrate with multi-quantum-well (MQW) active layers, and the facets coated with anti-reflectance layer. The laser features large spectral width, the high power, high polarization dependence and low ripple
