Patent ID: 6941047

Claim:
An integrated optical assembly, comprising: a fiber collimator that redirects and collimates a light beam from an optical source input, creating a collimated light beam; at least two focusing optical subassemblies, the at least two focusing optical subassemblies being aligned along a common axis; a connector housing that receives a fiber optical connector; a ledge structure adapted for positioning a printed circuit board, the printed circuit board being parallel to, and at a distance from, aspheric lenses of the focusing optical subassemblies when positioned on the ledge structure; and an optically transparent block that receives the collimated light beam from the fiber collimator, the optically transparent block having a top side coated to act as a reflective mirror and a bottom side including thin film filters (TFFs), each with a different passband wavelength and each being positioned over each focusing optical subassembly, the top side being the side opposite to at least one of the fiber collimator and the focusing optical subassemblies, wherein the collimated light beam travels in a zig-zag fashion within the optically transparent block, wavelength components of the collimated light beam being separated from each other by the TFFs with matching passband wavelengths and focused by the focusing optical subassemblies below the TFFs.
