Vertical-cavity Surface-emitting Lasers (VCSELs): Technologies and Global MarketsLONDON, August 7, 2018 /PRNewswire/ -- Report Scope Summary Vertical-cavity surface-emitting lasers (VCSELs) are specialized laser diodes that revolutionized the fiber optic communications industry by increasing data speed and improving efficiency.VCSELs are semiconductor lasers or laser diodes with monolithic laser resonators, where the light emitted leaves the device in a perpendicular direction to the surface of the chip. The cavity or resonator is achieved with two semiconductor Bragg mirrors. Between these mirrors is an active region known as a quantum well, which is so narrow that quantum confinement occurs. These lasers, which were previously called edge-emitting diodes, emit infrared or coherent energy parallel to the surface between semiconductor lasers; VCSELs emit their infrared or coherent energy perpendicular to the surface between these semiconductor layers. Due to this fact, the surface area covered by VCSELs is smaller, resulting in less time lag to transfer the data in optical devices. Another factor that makes VCSELs superior to their competitors is in their production process.While edge emitters cannot be tested until the end of the production process, VCSELs can be tested at any time in the production process. This saves time for manufacturers and leads to a higher-quality product in the end. Other advantages of VCSELs over edge-emitting diodes include lower manufacturing costs, higher speeds, more energy efficiency and their being easier to test.The intensity at which VCSELs emit a narrow, more cylindrical beam is much faster than other emitting diodes. Due to this, energy loss is minimal, and a higher rate of transfer can be attained. At present, VCSELs are used across a wide spectrum, ranging from 600 nanometers (nm) to 1,400 nm.However, the major challenge today is the development of a high-powered VCSEL device that emits a wavelength of 1,550 nm. In the overall electromagnetic spectrum, these wavelengths respond to the infrared region. Materials used to manufacture VCSELs include gallium nitride (AlGaAs), gallium arsenide (GaAs), indium phosphide (InP) and indium gallium arsenide nitride (InGaAsN). VCSELs are expected to be a prominent source in the optical communications market in the coming years. Other applications, such as gesture recognition and industrial sensing, will spur the demand for VCSELs in the future.
