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 isolator has optical fibers arranged on a single side. The optical isolator includes an input optical fiber, an output optical fiber, an input splitting/combining device, an output splitting/combining device, an input optical rotation device, an output optical rotation device, a lens, a Faraday rotator, and a reflector. The input optical fiber and the output optical fiber are on a same side of each of the lens, the Faraday rotator, and the reflector. The optical isolator with input and output optical fibers arranged on a single side only needs to use one lens. The input and output splitting/combining devices are fixed on an end surfaces of input/output optical fibers, respectively.
