ABSTRACT:
The present invention relates to a method of aligning and assembling an optical demultiplexer module having an input fiber, a collimator lens, a diffraction grating, and a photodetector array, and a mechanism for automatically aligning such an optical demultiplexer module. The method comprises the steps of preparing a submodule A including the input fiber and the photodetector array and a submodule B including the diffraction grating and the collimator lens, preparing an alignment jig for allowing the submodules A, B to move independently of each other, fixing the submodules A, B to the adjustment jig, and applying light from the input fiber and moving the submodule B with respect to the submodule A for maximizing a light output from a photodetector.
