Abstract
An optomechanical system including a guide structure, to guide a light beam; and two waveguide segments. Each guide structure include beams that together form two combs partially nested one in the other. At least one beam is free to move in translation along an axis orthogonal to the long axis of the guide structure. A displacement into an optical phase shift, while limiting additional effects on the intensity.
Claims14
An optomechanical system for transduction of a displacement into an optical phase shift, comprising:
- at least one guide structure, adapted to guiding a light beam (F) centred on a predetermined wavelength called the guided wavelength;
- and
- at least two waveguide segments, each arranged to carry a light beam as far as the at least one guide structure, or to move a light beam emerging from the at least one guide structure to a distance.
- wherein:
- at least one guide structure comprises a plurality of beams parallel to each other, distributed one after the other along a long axis of the guide structure, and arranged in two combs partly nested one in the other;
- and
- at least one guide structure, at least one beam is mobile, free to move in translation relative to the other beams of the same guide structure along an axis orthogonal to the long axis of the guide structure.
