Tunable reflectors based on multi-cavity interference

摘要

A reflective structure includes an input/output port and an optical splitter coupled to the input/output port. The optical splitter has a first branch and a second branch. The reflective structure also includes a first resonant cavity optically coupled to the first branch of the optical splitter. The first resonant cavity comprises a first set of reflectors and a first waveguide region disposed between the first set of reflectors. The reflective structures further includes a second resonant cavity optically coupled to the second branch of the optical splitter. The second resonant cavity comprises a second set of reflectors and a second waveguide region disposed between the second set of reflectors.

1. A tunable reflector structure comprising:
an input/output port; an optical splitter coupled to the input/output port; a first resonant cavity coupled to a first output of the optical splitter; a second resonant cavity coupled to a second output of the optical splitter; wherein at least one of the first resonant cavity or the second resonant cavity include a phase control element and the first resonant cavity and the second resonant cavity form a loop with the optical splitter.
