Abstract: An optical modulator may include a lower waveguide, an upper waveguide, and a dielectric layer disposed therebetween. In one embodiment, the lower waveguide may include a u-shaped region within an optical mode of the light passing through the optical modulator. By conforming the dielectric layer to the surfaces of the u-shaped region, the amount of area of the dielectric layer within a charge modulation region is increased relative to forming the dielectric layer on a single plane. Folding the dielectric layer in this manner may improve modulation efficiency. In one embodiment, the u-shaped region is formed by using ridge structures that extend from an upper surface of the lower waveguide towards the upper waveguide. To aid in lateral confinement of the optical mode, the dielectric layer may be deposited on one side surface of the ridge structures while a different dielectric material is deposited on the opposite side surface.

Abstract: Embodiments of the present disclosure include devices that split a light beam into two separate paths, with reduced sensitivity to fabrication variation. The devices can operate as 3-dB splitters that divide the input optical energy equally between two output waveguides. Similarly, the devices can also function to combine two light beams into a single path (coupler). The designs make use of adiabatic modal evolution and do not require physical symmetry along the entire device length. The devices inlcude first and second waveguides, each having a transition section, which may be tapered, the transition disposed adjacent to each other defining a gap therebetween, such that optical energy couples between the waveguides.

Abstract: An optical coupling may involve orienting a waveguide and a lens such that light rays are focused on a surface. The lens may involve the use of a material having a variable refractive index to focus rays of light along first axis and a curved surface to focus the rays of light along a second axis.
