ABSTRACT:
This invention eliminates the lens/prism assemblies and the multiple pick-up fibers that must be multiply lensed to a detector to get sufficient signal strength for the system to work. This invention also compensates for some of the rapid rise and fall time of the present system. A single pick-up, either a fiber or a photodiode, is placed at the end of a waveguide. A lens or lens system is used to focus a single optical signal on to the fiber face or the photodiode active area. Various light injection techniques, such as fibers, fiber/lens assemblies, lensed VCEL, lasers, or LEDs can be utilized because of the location in the system.
