Vertical-Cavity Surface-Emitting Lasers (VCSELs) are semiconductor lasers that emit light perpendicular to the surface of the chip. They are widely used in various applications such as optical communication, consumer electronics, and sensing. VCSELs have several advantages over edge-emitting lasers, such as low cost, compact size, high power efficiency, and the ability to be monolithically integrated with other components.
Multimode VCSELs are a special type of VCSELs that have multiple transverse modes of operation. This allows them to emit multiple beams at the same time, with each beam having a different beam profile.
This makes them ideal for applications such as consumer electronics, where a wide area of illumination is desired. Multimode VCSELs also have the advantage of being able to operate over a larger range of wavelengths, making them useful for applications such as optical communication.
The fabrication of multimode VCSELs involves the use of specialized fabrication techniques, such as electron-beam lithography, to create the multiple transverse modes. Additionally, the laser structure must be designed such that the multiple beams are well-collimated and have a relatively uniform beam profile. This ensures that the beams can be efficiently coupled into an optical fiber for applications such as optical communication.
Multimode VCSELs have the potential to revolutionize the way we use light in various applications. They offer the advantages of being compact, low-cost, and highly efficient, while also having the potential to be monolithically integrated with other components. In short, multimode VCSELs are a powerful and versatile tool for optical applications.
The Global Multimode VCSEL market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
