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.
