Abstract
A beam steering structure includes an alignment structure shaped to receive and align an optical fiber such that an axis of a core of the optical fiber is oriented in a first direction. The beam steering structure includes an end portion having an angled optical surface oriented at a non-zero angle relative to the first direction. The end portion is shaped and positioned so that light propagating along the first direction from the optical fiber passes through the end portion to reach the angled optical surface. A reflecting system is positioned on the angled optical surface across the first direction. The reflecting system is configured to reflect incident light propagating along the first direction into a first reflected beam of a first polarization and a second reflected beam of a second polarization. The first and second reflected beams are directed into first and second optical communication channels, respectively.
