System and method for nano-opto-mechanical-fluidic sensing of particles
First Claim
Patent Images
1. A system comprising:
- a resonator, the resonator comprising a beam and a nanochannel passing through the beam, the resonator further comprising a photonic crystal positioned in the beam and adjacent the nanochannel, where the nanochannel contains a liquid, and where the liquid contains particles to be sensed,where the photonic crystal confines light in a photonic mode, the beam confines sound in a mechanical mode, and motion within the mechanical mode modifies the photonic mode;
an optical fiber coupled adjacently to the resonator, the optical fiber to guide a light wave past the resonator, anda detector positioned at an output of the optical fiber, where the detector detects changes in the light wave to detect a mechanical property of the particles based on the confined sound and a position of the particles based on the confined light.
