| 英文摘要 | An optical coupling device (100) can couple incident light from a fiber into waveguides, but can reduce the coupling of return light from the waveguides into the fiber. A Faraday rotator layer (112) can rotate by forty-five degrees, with a first handedness, respective planes of polarization of incident beams, and can rotate by forty-five degrees, with a second handedness opposite the first handedness, respective planes of polarization of return beams. A redirection layer (116) can include at least one grating coupler (118) that can redirect an incident beam of one polarization so that the redirected path (120) extends within the redirection layer toward a first waveguide, and can redirect an incident beam of an opposite polarization so that the redirected path (122) extends within the redirection layer toward a second waveguide. An optional birefringent layer (602) can spatially separate incident beam having different polarizations, so that two single-polarization grating couplers (604, 606) can be used. |
