Abstract: An asymmetric adiabatic polarization beam splitter integrated with a waveband filtering splitter unit and a polarization filtering splitter unit is capable of being packaged to form an integrated optical waveguide filtering chip. The waveband filtering splitter unit utilizes an adiabatic optical waveguide structure and stimulated Raman adiabatic passage on an optical waveguide to split the energy of light sources of different bands to different spaces when the light energy is performed with an adiabatic process. The polarization filtering splitter unit utilizes the two orthogonal polarization modes of an optical waveguide with birefringence to achieve a polarization-dependent mode splitting effect based on an adiabatic theory. The asymmetric adiabatic polarization beam splitter realizes the characteristics of integration and high process tolerance, and improves the mass production feasibility.

Abstract: An adiabatic coupling phase modulation module has an optical substrate, an asymmetric adiabatic coupling polarization beam splitter and two electro-optical phase modulators. The asymmetric adiabatic coupling polarization beam splitter performs band spatial filtering on a quantum light source signal to output a light source signal of a specific wavelength band, and performs polarization spatial filtering on the light source signal of specific wavelength band to output a first orthogonal polarization direction light source signal of the specific wavelength band and a second orthogonal polarization direction light source signal of the specific wavelength band. The two electro-optical phase modulators respectively perform phase coding processes on the first orthogonal polarization direction light source signal and the second orthogonal polarization direction light source signal.

Abstract: An integrated biplane optical sensing core chip has a non-linear optical substrate, a first waveguide structure, a second waveguide structure and a waveguide coupled fiber. The non-linear optical substrate, the first waveguide structure and the second waveguide structure are made of the same nonlinear optical material. The first waveguide structure is connected to the second waveguide structure via a waveguide coupled fiber is outside and independent to the non-linear optical substrate. Therefore, the first waveguide structure and the second waveguide structure can overlap in the vertical direction, and can be set close to each other in the horizontal and vertical directions, so the integrated biplane optical sensing core chip can be miniaturized and can meet reciprocity. The integrated biplane optical sensing core chip is suitable for an optical fiber sensor, and the optical fiber sensor can be a fiber-optic gyroscope or a fiber-optic current sensor.
