    摘要： Embodiments herein relate to a photonic integrated circuit (PIC) with an on-chip optical isolator. The PIC may comprise a laser, a waveguide coupled with the laser, and a closed loop resonator coupled to the laser through the waveguide. A magneto-optical (MO) layer is over and in contact with the waveguide and the closed loop resonator. The closed loop resonator may comprise a first polarization rotator (PR) and a second PR. A light from the laser in transverse electric (TE) mode through the waveguide is rotated in the first PR to a light in transverse magnetic (TM) mode, and the light in TM mode is rotated in the second PR to light in TE mode. The isolator may further comprise a micro-heater over or along a side of the waveguide and separated from the closed loop resonator; and a feedback control loop connected to the closed loop resonator and the micro-heater.

    摘要： Various optical isolators are disclosed. One embodiment provides an optical isolator comprising a waveguide that includes polymer magneto-optical media. In a particular embodiment, the waveguide is dimensioned for single mode operation in the selected isolation range. A cross-section of the waveguide is inhomogeneous in terms of magneto-optical materials. Polymer magneto-optical material is a part of the optical waveguide structure. The inhomogeneity induces the propagation constant shift, which is propagation-direction-dependent. An embodiment is characterized by a cutoff frequency for forward propagating waves that is different than the cutoff frequency for reverse waves; the dimensions and direction of magnetization of the waveguide can be tailored so that, in a particular embodiment, the cutoff frequency for forward propagating waves is lower than the cutoff frequency for reverse waves.
