Abstract

This paper describes a low-cost thin-film filters (TFF) multiplexing/demultiplexing (MUX/DEMUX) module based on high-precision injection molding. We have developed two technologies to markedly reduce the cost of the module: (1) an optical system that uses concave micromirrors to loosen the alignment tolerance of the parts, and (2) an injection-molded block with integrated structures that align fibers, filters, and mirrors passively to reduce assembly time
