The Superluminescent Diodes (SLD) is a Semiconductor device to emit low-coherence light of a broad spectrum like LED, But high brightness like LD, Laser Diode. The Light Emitted in a narrow active layer similar to LD can be efficiently incident to the fiber. SLD is usually used as an incoherent light source for optical sensors like OCT and Optical fiber gyroscopes. The mechanism of SLD emission is the same as the semiconductor laser (LD) and light emitting diode (LED). Emission occurs by moving forward current to a P-N junction. When a power supply is connected to the player positive and the N-layer negative, Electrons enter from the N-side and holes from the p-side.
Superluminescent Diodes are designed to have large Single-Pass amplification for the natural emission generated along the waveguide, But Laser Diodes insufficient feedback to achieve lasing action. Superluminescent Diode is excellent high power broadband light sources that are ideal for use in some applications such as Fiber Optic Link Testing, WDM PON systems, White Light interferometry, and many other applications.
