What is a Quartz V-Groove Substrate?
Quartz V-groove substrates are ultra-high precision structures etched or machined into high-purity quartz glass. These substrates are designed to accurately align optical fibers with micron or sub-micron tolerance, making them essential for use in photonic integrated circuits, planar lightwave circuits (PLC), and fiber array units (FAU). Our Quartz V-Groove Substrate ensures stable optical coupling and high alignment accuracy, ideal for optical communication systems.
