Planar Tees and Couplers for Multimode Devices
Multimode fiber-optic systems currently use couplers for data distribution to several user terminals. Couplers are made by modifying the optical fibers (fusing, tapering, lapping and gluing) or with micro-optic components (such as microlenses and beam splitters). These two approaches and the planar approach, which is the subject of this program, are shown in Figure 1. Good couplers have been demonstrated using micro-optic methods, although several key questions have been encountered when attempting to transfer the technology to a manufacturing process.
