Abstract
An optics system is provided that comprises a glass-based diffractive optical element (DOE) for coupling an optical signal passing out of an optical waveguide into a photodetector. The glass-based DOE improves optical link performance by performing one or more of shortening a response time of a photodetector, preventing an overloading condition of the photodetector from occurring and managing back reflection of light from the photodetector. The glass-based DOE is relatively inexpensively to manufacture and is reliable over a wide range of temperatures.
