Abstract: A single-ended output circulator includes a three-core optical fiber head having first, second, and third optical fiber cores; a walk-off crystal having a first surface facing towards the second end of the three-core optical fiber head tube and a second surface facing away from the second end of the three-core optical fiber head tube; a plurality of half-wave plates each having a first surface coupled to the second surface of the walk-off crystal and a second surface facing away from the second surface of the walk-off crystal; a collimating lens having a first end and a second end; a reflection mirror configured to reflect light beams from the collimating lens; an optical prism between the collimating lens and the reflection mirror and configured to transmit a light beam along a propagation direction according to a polarization direction of the light beam; and a polarization rotator.

Abstract: An optical switch includes an array of optical fibers to conduct optical signals. A biconvex lens has a front convex surface facing the fibers' tips and has a back convex surface facing a microelectromechanical (MEMS) mirror. The MEMS mirror can be selectively oriented to reflect the optical signals incident to the MEMS mirror so the optical signal input from one fiber can be selectively routed to another of the fibers.
