Systems and methods for nonlinear optical light generation using linearly uncoupled resonators in integrated photonic devices

A method, comprising:

• receiving a first light at a plurality of resonators, each resonator from the plurality of resonators having a set of resonance frequencies independently selected from a set of resonance frequencies of each remaining resonator from the plurality of resonators to substantially avoid any linear coupling among the plurality of resonators;
• defining a spatial overlap region between at least two resonators from the plurality of resonators such that nonlinear optical processes are substantially optimized to produce a second light based on the first light;
• and
• sending the second light from the plurality of resonators.

An apparatus, comprising:

• a first optical resonator having a set of resonance frequencies and producing an optical field during operation;
• a second optical resonator not linearly coupled to the first optical resonator, the second optical resonator having a set of resonant frequencies different from the set of resonance frequencies of the first optical resonator, the second optical resonator producing an optical field during operation that at least partially overlaps with the optical field of the first optical resonator during its operation to produce nonlinear optical processes;
• a first optical channel operatively coupled to the first optical resonator;
• and
• a second optical channel operatively coupled to the second optical resonator.
