Abstract
A micro-optical element includes a resonator substrate, at least one microresonator includes a rotationally symmetrical body mounted on the resonator substrate, and a light-reflecting element including a ring-shaped mirror that surrounds the rotationally symmetrical body.
Claims12
A micro-optical element comprising:
- a resonator substrate;
- at least one active optical microresonator including a rotationally symmetrical body and being disposed on the resonator substrate;
- a light-reflecting ring-shaped mirror that surrounds the rotationally symmetrical body such that the rotationally symmetrical body does not touch the light-reflecting ring-shaped mirror;
- and
- an at least partially optically transparent cover through which light emitted least one active optical microresonator can be guided,
- wherein the resonator substrate, the light-reflecting ring-shaped mirror, and the at least partially optically transparent cover are disposed so as to form a fluid chamber around the at least one active optical microresonator.

A micro-optical array comprising:
- at least one resonator substrate;
- and
- at least two array elements disposed on the substrate, each array element including:
- one or more active optical microresonators, each having a rotationally symmetrical body;
- one or more light-reflecting ring-shaped mirrors surrounding the rotationally symmetrical body;
- and
- an at least partially optically transparent cover through which light emitted by the one or more active optical microresonators can be guided,
- wherein the resonator substrate, each of the one or more light-reflecting ring-shaped mirrors, and the at least partially optically transparent cover are disposed so as to form one or more fluid chambers around each of the one or more active optical microresonators.

An optical sensor system comprising:
- a device configured to excite the emission of light from at least one microresonator;
- a micro-optical element including:
- a resonator substrate,
- at least one microresonator having a rotationally symmetrical body and being disposed on the resonator substrate, and
- a light-reflecting ring-shaped mirror that surrounds the rotationally symmetrical body such that the rotationally symmetrically body does not touch the ring-shaped mirror;
- an at least partially optically transparent cover including one or more fluidic inlets and one or more fluidic channels configured to feed an analyte to and remove an analyte from the at least one microresonator;
- and
- a detector circuit configured to detect a frequency shift in the light emitted by the at least one microresonator.
