  • Patent number: 11906778
    Abstract: Configurations for an optical splitter are disclosed. The optical splitter may include an input waveguide, a free propagation region, and an array of output waveguides. The input waveguide may be sufficiently narrow that the light in the free propagation region may diffract and provide the same optical intensity at far field angles across a wide wavelength range. The input waveguide may have a high V number in a vertical dimension and a low V number in a horizontal dimension. Because all of the wavelengths of light diffract at the same angle in the free propagation region, once the light reaches the output waveguides, the light may have similar optical power at each of the output waveguides. Additionally, the output waveguides may vary in width and spacing to mitigate the non-uniform optical power distribution of the phase front of light.

  • Patent number: 11906780
    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.
