Manufacturing of lithium niobate integrated optic devices
Integrated optical devices are now commercially available from several sources. Several companies are offering integrated optical circuit products for sale. This indicates that many of the initial difficulties have been overcome. Commercialization activities for a merchant market are currently underway at Amphenol Products, Crystal Technology Inc. (CTI), Barr & Stroud, and British Telecom—DuPont (BT-D). Product announcements have appeared for both phase modulators, amplitude modulators, and an optical switch. These and other more advanced devices are now commercially available with pigtailed optical fibers.
