We present a novel surface-normal optical wavelength-division-demultiplexer (WDDM), working at 750, 770, 790, 810, 830 and 850 nm wavelengths. The device is based on an integration of a planar waveguide, a substrate waveguide and waveguide holograms. The unique optical in-plane to surface-normal conversion converts the difficult three spatial and three angular edge coupling problem into a planar surface one, resulting in a practical compact face-to-face packaging between the photodetector array and the demultiplexer. A six-channel wavelength-division-demultiplexer with equally spaced collinear surface-normal outputs are designed and demonstrated in a polymer-based planar waveguide in conjunction with holograms on a glass substrate.
