The rapid explosion of growth of the Internet has created a demand for increased bandwidth. All optical networks are becoming important in filling this bandwidth gap. Optical interference filters are enabling technologies that provide management of light in optical switching, multiplexing, demultiplexing and transmission of optical signals. Low Pressure Chemical Vapor Deposition (LPCVD) is a deposition technique uniquely qualified to provide uniform durable optical interference coatings on fiber optic components of complex shapes where the size of components ranges from 200 microns to 6 mm.
