    摘要: Photonic devices are disclosed including a first cladding layer, a first electrical contact comprising a first lead coupled to a first dielectric portion, a second electrical contact comprising a second lead coupled to a second dielectric portion, a waveguide structure comprising a slab layer comprising a first material, and a second cladding layer. The slab layer may be coupled to the first dielectric portion of the first electrical contact and the second dielectric portion of the second electrical contact. The first dielectric portion and the second dielectric portion may have a dielectric constant greater than a dielectric constant of the first material.

    摘要: An apparatus for polarization state generation and phase control includes a Stokes Basis generator to generate multiple Stokes Bases from one or more input beams, an intensity modulator to modulate an intensity of each of the Stokes Bases, and a beam combiner to combine the modulated Stokes Bases into an output beam. A method of polarization state generation and phase control includes generating multiple Stokes Bases from an input beam; modulating an intensity of each of Stokes Bases; and combining the modulated Stokes Bases into an output beam.

    摘要: An optical coupling device can include a first birefringent layer having opposing first and second surfaces. The first birefringent layer can split incident light received at the first surface into first and second beams. The first and second beams can have respective polarization orientations that are orthogonal to each other. The first birefringent layer can propagate the first and second beams along respective first and second paths within the first birefringent layer to the second surface. The first and second beams can be spatially separated at the second surface. A redirection layer facing the second surface of the first birefringent layer can include first and second grating couplers configured to respectively redirect the first and second beams to propagate within the redirection layer as respective third and fourth beams. In some examples, the third and fourth beams can have respective polarization orientations that are parallel to each other.
