The arrays are manufactured using Pyrex V-Groove substrates in conjunction with a Pyrex lid or precision silicon wafer V-Groove, enabling sub-micron alignment accuracy with UV cure attachment capabilities. Our high-precision fiber arrays are engineered to meet rigorous technical specifications, enabling customers to define critical parameters such as channel count, fiber spacing, fiber types, face grinding angles, and overall dimensions. The manufacturing process is optimized to achieve minimal. and data center applications. Optical Arrays are used in optical switching and in. The PM V-Groove arrays are mass produced to be incorporated in various photonic devices, particularly for high speed 40 Gb/s to next generation 100 Gb/s coherent detection systems.
