Abstract
An optical multiplexer and methods of making and using the same are disclosed. The multiplexer generally includes a beam splitter and a polarization beam splitter. The beam splitter is generally configured to combine first and second polarized optical signals by reflecting a first polarized optical signal towards a first target and allowing a second polarized optical signal to pass through towards the first target. The polarization beam splitter is generally configured to combine the first and second polarized optical signals with a third polarized optical signal by either (i) reflecting the third polarized optical signal towards a second target and allowing the first and second polarized optical signals to pass through towards the second target, or (ii) reflecting the first and second polarized optical signals towards the second target and allowing the third polarized optical signal to pass through towards the second target.
