N-GaAs substrate VCSEL epiwafer 6 inch GaAs orientation 100 111 wavelength 940nm for Gigabit Ethernet
N-GaAs substrate VCSEL epiwafer‘s brief
The N-GaAs (n-type Gallium Arsenide) substrate VCSEL epiwafer is a critical component used in the fabrication of Vertical-Cavity Surface-Emitting Lasers (VCSELs). VCSELs are key in applications like high-speed optical communication, 3D sensing, and LIDAR. The wafer is built on an N-type GaAs substrate, which provides excellent electrical conductivity and a suitable base for epitaxial layer growth.
Epitaxial layers, typically composed of various compound semiconductors, are grown on the substrate to form the laser's active region. This structure allows for the vertical emission of light, offering high efficiency and easy integration into arrays. The wafer typically supports emission at wavelengths like 850 nm or 940 nm, ideal for applications in fiber optic communication and 3D sensing.
N-GaAs substrates provide low defect density, essential for high-performance devices, and can withstand high-temperature processing. Its mechanical stability and thermal conductivity make it suitable for high-power and high-speed applications. This wafer is commonly used in data centers, consumer electronics (e.g., facial recognition in smartphones), and automotive systems like LIDAR, due to its cost-effective and scalable production.
