FP(Fabry-Perot)) Epiwafer InP substrate's abstract
Fabry-Perot (FP) Epiwafer on Indium Phosphide (InP) substrates is a critical component in the fabrication of high-performance optoelectronic devices, particularly laser diodes used in optical communication systems. The InP substrate offers excellent lattice matching with materials such as InGaAsP, enabling the growth of high-quality epitaxial layers. These wafers typically operate in the 1.3 μm to 1.55 μm wavelength range, making them ideal for fiber-optic communication due to the low-loss characteristics of optical fibers in this spectrum. FP lasers, grown on these epiwafers, are widely used in data center interconnects, environmental sensing, and medical diagnostics, providing cost-effective solutions with good performance. The simpler structure of FP lasers compared to more complex designs like DFB (Distributed Feedback) lasers makes them a popular choice for medium-range communication applications. InP-based FP epiwafers are essential in industries that require high-speed, reliable optical components.
