    摘要： In some implementations, an optical isolator core includes a Faraday rotator and a plurality of birefringent crystal plates. The plurality of birefringent crystal plates may include a first birefringent crystal plate to separate input light into light having a first polarization and light having a second polarization, and a second birefringent crystal plate to combine the light having the first polarization and the light having the second polarization in output light that is laterally displaced by the single stage optical isolator. The Faraday rotator may be provided between the first birefringent crystal plate and the second birefringent crystal plate. In some implementations, the plurality of birefringent crystal plates further include a third birefringent crystal plate provided between the Faraday rotator and the second birefringent crystal plate. Additionally, or alternatively, the optical isolator core may further include a half-wave plate arranged between the Faraday rotator and the first birefringent crystal plate.

    摘要： A wavelength tunable laser includes a filter region having a wavelength selection function on light from a gain region, wherein the filter region is a Sagnac interferometer and includes two ring resonators. The ring resonator has two optical couplers, and first and second curved waveguides connecting the two optical couplers, each of the two optical couplers is configured to receive input of the light from the gain region through an input-output port, to couple light of a resonant peak to a bar port of the input-output port, and to couple light except light at a resonant peak wavelength to a cross port of the input-output port, and each of radiation waveguides connected to the cross ports of the input-output ports of the two optical couplers has a structure that radiates the light except the light at the resonant peak wavelength to a front surface or a back surface of a substrate.

    摘要： The present invention relates to a plasmonic optical waveguide using plasmonic coupling between a nano-aperture and a nano-particle. The plasmonic optical waveguide includes the nano-aperture formed with an opening of a nano-scale through which light enters; and a single metal nano-particle arranged at the focal point of the nano-aperture to generate plasmon coupling in association with the light output from the nano-aperture. The plasmonic optical waveguide has an effect of forming a small and strong high-intensity high-density light spot of a sub-wavelength size, in which an amplification rate is increased at the output surface of the nano-particle more than a few hundred times compared with the incident light, since the light is transmitted by plasmon coupling generated between the nano-aperture and the nano-particle.

    摘要： A system for conversion or amplification using quasi-phase matched nonlinear optical wave-mixing comprises a first radiation source for providing a pump radiation beam, a second radiation source for providing a signal radiation beam, and a bent structure for receiving the pump radiation beam and the signal radiation beam. The radiation propagation portion of the bent structure is made of a uniform nonlinear optical material and the radiation propagation portion comprises a dimension taking into account the spatial variation of the nonlinear optical susceptibility along the radiation propagation portion as experienced by radiation travelling along the bent structure for obtaining quasi-phase matched nonlinear optical wave-mixing in the radiation propagation portion. The dimension thereby is substantially inverse proportional with the linear phase mismatch for the nonlinear optical process. The system also comprises an outcoupling radiation propagation portion for coupling out an idler radiation beam generated in the bent structure.
