Title:
MZI-MAGNETO-OPTICAL ISOLATOR PHOTONIC INTEGRATED CIRCUITS AND DEVICES FOR PHOTONIC SENSING
Document Type and Number:
WIPO Patent Application WO/2017/190064
Kind Code:
A3
Abstract:
A system includes a Mach-Zehnder cirulator isolator. The Mach-Zehnder structure includes a substrate, a plurality of waveguides (128) disposed on the substrate, and a magneto-optic material (132) coupled to the plurality of waveguides. The Mach-Zehnder structure also includes one or more magnets configured to couple to the magneto-optic material and induce a magnetic field (see arrwos) in the magneto-optic material, wherein the Mach-Zehnder structure is configured to induce a non-reciprocal phase shift on light propagating in the plurality of waveguides. The system also includes one or more phase tuning elements (148) coupled to the Mach-Zehnder structure and configured to tune the phase shift.
