Abstract:
To reduce or eliminate crosstalk between adjacent integrated optical waveguides, an embodiment of an integrated structure includes, between the optical waveguides, a metal isolation region configured to redirect a signal leaking from one waveguide away from the other waveguide, to absorb the leaking signal, or both to redirect and absorb respective portions of the leaking signal. For example, such an integrated structure includes a cladding, first and second optical cores, and a metal isolation region. The optical cores are disposed in the cladding, and the isolation region is disposed in the cladding between, and separate from, the cores. Including a metal isolation region between adjacent optical waveguides can reduce crosstalk between the waveguides more than coating the waveguides with a metal because the metal coating typically is not thick enough to redirect or absorb enough of a leakage signal to reduce crosstalk to a suitable level.

Claim (Index 1):
An integrated structure, comprising:\n a cladding having an outer perimeter; first and second optical cores disposed in the cladding; and an isolation region including a metal, disposed in the cladding between, and separate from, the first and second optical cores, and extending to the outer perimeter of the cladding.
