A superluminescent diode (SLD) is a semiconductor light-emitting device that emits light over a wide range of wavelengths. They are typically used in optical fiber communication systems as broadband light sources.  SLDs are made of semiconductor materials such as gallium arsenide and aluminum gallium arsenide. The active region of an SLD typically contains one or more quantum wells. In operation, electrons and holes are injected into the quantum well where they recombine and emit light.  The wavelength of the light emitted by an SLD is determined by the size of the quantum well. SLDs can be fabricated to emit light over a wide range of wavelengths from the visible to the infrared. SLDs typically have a very broad emission spectrum with a full width at half maximum (FWHM) of 20-40 nm. This makes them ideal for use as broadband light sources in optical fiber communication systems.  Superluminescent diodes are also very efficient light sources. They have a quantum efficien...

Optical coherence tomography (OCT) is a rapidly growing, advanced technology that has transformed ophthalmology practice. OCT is widely employed in the medical profession. It is based on low-coherence interferometry, and a focused probe may be utilized to acquire the reflectivity profile of material along an optical axis. There are two types of OCT imaging: TD-OCT and SD-OCT. Both have their own advantages and disadvantages, so which one is better for broadband light source imaging? TD-OCT uses a time-domain imaging method, which means that it captures light that is scattered at different depths in the tissue. This results in a more detailed image, but it also takes longer to capture. SD-OCT uses a spectral-domain imaging method,  it captures light that is scattered at different wavelengths. This results in a less detailed image, but it is much faster. So, which one is better? It depends on what you need. If you need a detailed image, then TD-OCT is the better choice. If you need a...
