  Tunable laser sources are being used in telecommunications to meet various requirements such as performance optimization, channel security, wavelength conversion, and the replacement of fixed-wavelength distributed feedback lasers. External-cavity lasers have several advantages over other techniques, including high power, a broad tuning range, a high side mode suppression ratio, a narrow linewidth, and high performance, among others. The broadband gain chip is a superluminescent semiconductor diode that serves as both a broadband light source and a frequency-agile gain medium is at the heart of the external-cavity laser. What Is Gain Chip? Gain-chips are identical to laser diode chips except that they have a deep anti-reflective coating on one or both facets, which raises or eliminates the threshold of self-lasing. Furthermore, gain chips are divided into two categories: 1.       One side optical access (Type A and B) 2.     ...

Superluminescent diodes (SLDs) are widely used in medical fields such as ophthalmology, dermatology, gastroenterology, urology, gynecology, and otolaryngology, to name a few. The majority of applications employ SLD diodes with wavelengths ranging from 1000nm to 1550nm. Short temporal coherence, efficient coupling into single-mode fibres, divergence-limited light emittance, broad optical spectrum, presence of the optical waveguide, linear polarisation state, and amplified spontaneous emission are some of the factors that have made superluminescent light emitting diodes widely popular in medical fields. A.      SLD Diodes Applications in Ophthalmology: Let us now take a look at the role of the superluminescent diode in each of these applications. Superluminescent diodes are used in ophthalmology for Optical Coherence Tomography (OCT). OCT is a non-invasive imaging technique that takes cross-section pictures of your retina using low-coherence light waves. The oph...
