Fiber-coupled superluminescent diode (SLD) in 14-pin BTF package
Superluminescent diodes (SLD)
A superluminescent diode (SLD) is a semiconductor device, generating amplified spontaneous emission over a broad spectrum when biased in the forward direction. Unlike lasers, SLDs have a broad optical spectrum, making them suitable for various applications. SLDs lack the feedback to achieve lasing action. The suppression of the optical feedback is achieved by a tilted waveguide and anti-reflective coatings with <0.001% reflectivity, which allow for significantly reducing spectrum ripples. The peak wavelength and intensity of SLDs depend on active material composition and injection current. Certain SLDs manufactured by Innolume demonstrate high output optical power, exceeding 250mW, low spectral ripples and a broad spectrum. The width of the optical spectrum is important as it affects coherence length. Broader spectrum width can be beneficial for certain applications. SLDs, characterized by a high degree of spatial coherence, are effective for coupling into single-mode optical fibers. Innolume provides various packaging options, offering 14-pin modules with the availability of PM/HI fiber types, a loose tube, and a photodiode. Also, Innolume has the capability to provide configurations with the chip mounted on a submount, chip on a heatsink (e.g. C-Mount), or in a TO can.

Typical parameters of Superluminescent diodes (SLD)
SLD - main characteristics, features and application.
Superluminescent diodes (SLD) in essence are similar to laser diodes and operate based on electrically excited pn-junctions. When excited in the conductivity direction, this junction becomes optically active and generates amplified spontaneous emission (ASE) in a broad spectrum of wavelengths. The specific peak wavelength and intensity of SLD emission depend on the composition of the active material and the level of injected current. Unlike traditional laser diodes, SLDs are designed for high single-pass amplification of spontaneously emitted light along the waveguide, but they lack the necessary feedback to achieve laser action. This is efficiently achieved through a combination of tilted waveguides and anti-reflection coatings.
