Abstract
Optical multiplexers, optical demultiplexers, optical modules including the same, and methods of making and using the same are disclosed. The optical multiplexers include first and second structural blocks and a beam combiner. The first and second structural blocks each include at least one mirror and at least one filter, and are configured to combine a plurality of individual optical signals into a multi-channel optical signal. The beam combiner includes one or more mirrors and one or more filters, and is configured to combine the multi-channel optical signals into a further multi-channel optical output signal having the same number of channels as the multi-channel optical signals. The optical demultiplexers are structurally similar to the optical multiplexers, but provide a complementary or reverse function. The present multiplexers and demultiplexers reduce skew and/or accumulation of the geometric error over the channels in the multi-channel optical signal output from the multiplexer or input into the demultiplexer.
