Abstract
A passive optical circuit breaker includes a substrate and an optical waveguide assembly arranged relative to the substrate. The optical waveguide assembly includes a first optical waveguide portion having a first low-loss portion and a first high-loss portion, and a second optical waveguide portion having a second low-loss portion. The first low-loss portion and the second low-loss portion define a first optical path through the optical waveguide assembly, and optical energy directed through the first high-loss portion exceeding a prescribed threshold causes the first optical waveguide portion to physically deflect relative to the second optical waveguide portion and interrupt the first optical path through the optical waveguide assembly.
