The superluminescent diode refers to the semiconductor device which emits low coherence light such as LED which is Light Emitting Diode, with equivalently high beam light such as laser diode. The light passes through a narrow channel which is as same as Laser Diode. These semiconductors generally have applications in an optical sensor such as OCT and optical fibre sensor-based gyroscopes. As per the structure of the superluminescent diodes, the semiconductor emits in the wavelength of approximately 800 nm, 1300 nm, and 1550 nm categorized as Low, Medium and high. Though, these wavelengths fall under the visible domain. Generally, the power of the superluminescent diode ranges from High to Low which makes the broadband spectrum to be launched with the single diode fibre. The demand for the superluminescent diodes is attributed to increasing usage of the optoelectronic devices such as LED’s, photodiodes, phototransistors, imaging detectors and electronic imaging devices used in pathological laboratory industry for getting the body X-rays and other imaging solutions. This also aids in security checkpoints at railway, airports and other public spaces. With the advancements in technology, superluminescent diodes are developed to be calibrated with thermoelectric devices such as coolers, heaters with increasing efficiency and output. The Superluminescent diodes market is segmented By Type as Zinc Sulphide, Copper, Manganese, Other, By Mode into Powdered, Thin Film, and By Applications as Consumer Electronics, Automobiles, Industrial, Aviation, Others.
Under the COVID-19 pandemic, since the economic activities were at a halt at the lockdown stage there was not much demand amongst electronics, automobiles and other devices as the supply of raw materials were short, lack of workforce to drive the manufacturing sector and low capital funds with the corporates. However, in the medical industry, the demand for the imaging machines remained in momentum for CT scans, MRI and other diagnostics purposes. With the prevailing trend throughout the lockdown and in the current market, the demand for the superluminescent diodes been marginally improved. The demand in the unexpected times is expected to be led by its use in manufacturing by for inspecting raw material, It involves measuring the width and surface ruggedness for metal plates such as steel or in the thin films or checking for scratches and dents. In the medical industry, It is primarily used for Ophthalmology OCT and Intravascular OCT for ultrasounds.

Growing demand in the medical Industry
With the onset of the unexpected pandemic, the demand for the medical diagnostics market for regular health check-ups has been increased. The consumers are pro-actively been visiting the medical laboratories to get the thorough check-up done even if they observe few symptoms for early detection of any disease. This trend has increased the dependence on imaging devices which further have given the push to the superluminescent diodes market. The applications of superluminescent diodes in the medical industry can be cardiovascular imaging, and lungs. The machines provide high-resolution imagery insight for the specialists to diagnose the patients appropriately. For instance, Carestream has come up with modern medical imaging technology which has Digital Tomosynthesis and Dual Energy which offers to provide technicians with relevant information on diagnostics. Superluminescence technology aims to improve both over and underlying patients’ anatomy and visualization in 2D radiographs. Similarly, In December 2020, Nanox has developed and exhibited the demo version of Cold Cathode X-ray technology featuring a range of 2D and 3D imaging processes in a unique multi-source array structure at Radiology Society of North America (RSNA). Apart from the cardio and lungs x-ray devices, the technology is also used by ophthalmologists for Optical coherence tomography for cornea and retina diagnostics.
Demand in the automotive industry
The technology of superluminescence has been in the trend for the application of Gyroscope and other navigating instruments. Independent vehicles use gyroscopes to be used as navigator and stabilizer in the arena such as warzone, aerospace and underwater environments. Vehicles such as aeroplanes, jets and others require gyroscope technology. The technology can be used for a variety of applications such as line-of-sight stabilization for optical systems, the system for detecting earth rotation. Thus, advanced automotive need superluminescent diode powered gyroscopes that result in high performance and comes economic in terms of cost. The updates in Fiber Optic Gyroscopes have reduced the cost of its operations without compromising on the output to aid the navigation in automotive. Such advancements in the gyroscope is steered with the calibration capability of super luminescence diodes.
North America dominates the market for the superluminescent diodes. The market share can be attributed to the increasing trend in the advanced electric semiconductors such as optoelectronics, spintronics, quantum dots and electroluminescent. The demand also increases with quantum computing, cloud computing, miniaturization of devices and others. As per the demand for storage, electric vehicles, the internet of things emerge in Asia pacific in Japan, South Korea, the utility for superluminescent devices is expected to emerge leading it to hold a significant share for superluminescent diodes. The Asia-Pacific have great potential for the demand of superluminescent diodes given that there is the greater base for the structured and informal pathological lab market in countries such as India.
