Abstract:
1. An apparatus comprising: a first plurality of polarization-maintaining optical fibers configured to transmit a plurality of polarized optical signals, wherein the first plurality of polarization-maintaining optical fibers includes a first optical fiber configured to transmit a first polarized optical signal and a second optical fiber configured to transmit a second polarized optical signal; and a fiber-array plate configured to receive the first plurality of polarized optical signals from the plurality of polarization-maintaining optical fibers and emit a composite output beam that includes the first polarized optical signal and the second polarized optical signal, wherein the fiber-array plate includes a first surface and a second optical-signal-output surface, wherein the first plurality of polarization-maintaining optical fibers is fused to the first surface of the fiber-array plate, wherein the fiber-array plate includes a hollow inner chamber between the first surface and the second surface, and wherein the hollow inner chamber is air filled.
