Abstract
Official abstract text for this publication.
On-chip non-reciprocity can be achieved by employing micron-sized optomechanical (OM) devices that are fabricated on-chip and which can be integrated with other optical elements. Non-linear coupling between light and a mechanical mode inside a resonator can provide a non-reciprocal response of the OM system, which can be induced and fully controlled by an external driving electromagnetic field. By choosing different resonator and/or waveguide configurations and by tuning different system parameters, the same OM coupling mechanism can be used to provide isolation (e.g., as an optical diode), non-reciprocal phase shifting, and/or routing applications. Even in the presence of a finite intrinsic mode coupling inside the resonator, non-reciprocal effects remain large for a sufficiently strong OM coupling. The disclosed systems, methods, and devices can be applied on a single photon level, which may find use for various non-reciprocal applications in the classical optical as well as the quantum regime.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of non-reciprocal operation of a resonator system, the method comprising: pumping a resonator with a pumping electromagnetic field in one of a clockwise direction and a counter-clockwise direction of the resonator so as to enhance an optomechanical coupling of the resonator, the resonator having an intrinsic loss, κ in , at a same time as the pumping, propagating a first input electromagnetic field along a waveguide in a first longitudinal d…
