Abstract

An integrated optical XY coupler having two converging input waveguide arms meeting in a central section and a central output waveguide arm and two diverging flanking output waveguide arms emanating from the central section. In-phase light from the input arms constructively interfers in the central section to produce a single mode output in the central output arm with the rest of the light being collected in the flanking output arms. Crosstalk between devices on a substrate is minimized by this collection of the out-of-phase light by the flanking output arms of the XY coupler.

Optical coupler for heterogeneous integration

Patent Gehl, Michael; Vawter, Gregory A.; Hoffman, Galen

In an optical apparatus, an introduced semiconductor device is heterointegrated on a silicon-based platform containing a silicon-based waveguide. A polymeric waveguide is optically coupled to the introduced semiconductor device and overlies at least a portion of the silicon-based waveguide. The polymeric waveguide is conformed as a multimode interference (MMI) coupler between the introduced semiconductor device and the silicon-based waveguide. At least the polymeric waveguide, and in embodiments, also the silicon-based waveguide, is tapered with a shape that effectuates optical coupling to the silicon-based waveguide.

Integrated freeform optical couplers

Patent Yu, Shaoliang; Zuo, Haijie; Hu, Juejun; ...

Reflecting light beams off of microscale three-dimensional (3D) freeform surfaces can yield highly efficient coupling into and out of optical waveguides, optical fibers, and photonic chips. The structure of the 3D freeform reflective surface determines the shape of the reflected beam. This allows freeform reflectors to control the mode profile, rotation angle, and divergence angle of light beams. Control of beam shape enables mode matching between source output mode and target input mode, which results in low-loss optical coupling. An inventive freeform reflective surface can direct light beams in plane or out of plane via specular reflection or total internalmore » « less

Nonlinear optical coupler using a doped optical waveguide

Patent Pantell, Richard H [Menlo Park, CA]; Sadowski, Robert W [Stanford, CA]; Digonnet, Michel J. F. [Palo Alto, CA]; ...

An optical mode coupling apparatus includes an Erbium-doped optical waveguide in which an optical signal at a signal wavelength propagates in a first spatial propagation mode and a second spatial propagation mode of the waveguide. The optical signal propagating in the waveguide has a beat length. The coupling apparatus includes a pump source of perturbational light signal at a perturbational wavelength that propagates in the waveguide in the first spatial propagation mode. The perturbational signal has a sufficient intensity distribution in the waveguide that it causes a perturbation of the effective refractive index of the first spatial propagation mode ofmore » « less
