WDM & DWDM

WDM and DWDM components

Drawing on over 40 years of experience in the design and manufacture of high precision equipment for the sophisticated and diverse world of materials processing, Logitech has developed a fully integrated machine-technology package for the processing of Electro-Optic materials such as Lithium Niobate, Lithium Tantalate, Bismuth Silicon Oxide, barium Titanate to precise tolerances with scratch-free surface finishes.

Our flexible systems will integrate into your total fabrication programme, offering a quick and reliable route to success in the final preparation of your electro-optics material samples.

A fabrication process for a typical electro-optic device such as an optical phase modulator breaks down into 7 stages:

  • Manufacturing and opientation of the crystal.
  • Slicing the wafer from the crystal boule with an annular diamond saw.
  • Smooth lapping of both wafer faces and polishing of one or both faces to defect-free quality (sun nm Ra) .
  • Cutting of substrates from the polished wafer.
  • Forming of optical guide channels on the polished surface of the substrate e.g. by diffusion of a Ti strip.
