英文摘要 | Provided is an optical isolator using a photonic crystal. The optical isolator includes an input portion (50) including an input waveguide part (54) formed of the photonic crystal and an input waveguide (55) having a taper portion (52) formed in the input waveguide part. An output portion (70) includes an output waveguide part (74) formed of the photonic crystal and an output waveguide (72) formed in the input waveguide part continuously with the input waveguide. The output waveguide includes an another taper section having such an inclination that the light input in the backward direction is not coupled into the input portion. Alternatively the output region is constructed differently but always such that light input in the backward direction is not coupled into the input portion. An optical signal is transmitted in a forward direction from the input portion to the output portion and is not transmitted in a backward direction from the output portion to the input portion. |
