Method of operating a flying transducer particle in an optical waveguide, and optical waveguide including a transducer particle

摘要

A method of operating a transducer particle (2) in an optical waveguide (10) having a hollow core channel (11), wherein the transducer particle (2) is movably arranged in the core channel (11), comprises the steps of arranging the optical waveguide (10) in an external environment (1) of the optical waveguide (10), moving and/or positioning the transducer particle (2) by optical forces in the core channel (11), measuring a current position of the transducer particle (2) in the optical waveguide (10), and changing a condition of at least one of the transducer particle (2) and the external environment (1) by a mutual physical interaction of the transducer particle (2) and the external environment (1), wherein said condition is changed in dependency on the current position of the transducer particle. The method can be used e. g. for sensing a physical quantity of the external environment (1) and/or illuminating the external environment (1) in dependency on the current position of the transducer particle. Furthermore, an optical waveguide device (100) is described, which includes a movable transducer particle (2).
