Silicon V-groove technology in the volume production of optical devices

The use of optical devices in local loop applications is a major driver for products which have a reduced cost and size with significant improvements in performance over increased temperature ranges. The use of a silicon optical bench with an etched v-groove to locate the fibre provides an answer to all these. This has simplified assembly processes and facilitated volume manufacture, but equally important has provided a device whose alignment, unlike previous generations of product, is not affected by continuous temperature cycling
