Abstract: An isolator includes a substrate, a waveguide and an electronic circuit disposed above the substrate, and a non-reciprocal member disposed above the waveguide and the electronic circuit. The non-reciprocal member includes a first portion in contact with the waveguide and a second portion disposed within a predetermined range from the electronic circuit. Non-reciprocity in the second portion is weaker than non-reciprocity in the first portion.

Abstract: An isolator includes a substrate having a substrate surface, a waveguide, a groove, a mask, and a non-reciprocal member. The waveguide is disposed above the substrate surface and has a first surface facing the substrate surface, a second surface opposite the first surface, and a side face connecting the first surface to the second surface. The groove includes a bottom portion and a side portion configured to expose at least part of the side face of the waveguide. The mask is disposed above and overlaps at least a region of the second surface of the waveguide, as viewed in a direction normal to the substrate surface. The region of the second surface of the waveguide is in contact with the groove. The non-reciprocal member is disposed in the groove and is in contact with the side face of the waveguide.

Abstract: Provided is an optical body capable of arbitrarily and quickly controlling the optical characteristics of incident light. A refractive index variable layer (8) formed of PLZT or other material and a magneto-optical material layer (9) formed of garnet or other material are provided side by side between a first reflective layer (3) and a second reflective layer (5). If linearly polarized light is made incident from the side of the first reflective layer (3), the incident light interacts with the magneto-optical material layer (9) and is converted into a right-circularly polarized light component and a left-circularly polarized light component. A very small retardation occurring between both the right- and left-circularly polarized light components is amplified through multiple reflections between the pair of reflective layers (3, 5) and is controlled according to a controlled refractive index of the refractive index variable layer (8).
