| Abstract(in English) | We have constructed two parallel fiber-integrated optical isolators without precise optical alignment. The isolators are composed of an isolator chip using rutile wedges, and the backward losses are given by the tilt between the fibers and the optical beams. We have investigated excess insertion losses in the alignment-free integration and reduced them successfully. As a result, we have obtained the insertion losses of 0.91dB and 1.15dB and the backward losses of 31.4dB and 31.8dB at the wavelength of 1.555μm. In order to improve the backward losses, we have assembled an isolator chip with a new configuration and confirmed a large backward loss more than 50dB in preliminary experiments with optical alignment. |
