| 摘要 |
The present invention provides an optical isolator, including a planar lightwave circuit (10), a magneto-optic thin film (20), and a metal thin film (30) with a magnetic field. The planar lightwave circuit (10) is configured with a channel for transmitting an optical signal; the magneto-optic thin film (20) is disposed on the planar lightwave circuit (10), and a plane on which the magneto-optic thin film (20) is located is parallel to the channel for transmitting an optical signal; and the metal thin film (30) with the magnetic field is disposed on the magneto-optic thin film (20). |
