Implanting optical cavity structures
First Claim
1. An implantable product comprising:
- an optical cavity structure operating as an interferometer;
the optical cavity structure including;
first and second optical cavity parts, each operable as a respective optical cavity and each including a respective light transmissive portion, and wherein light input to the first and second optical cavity parts is reflected more than once across the respective light transmissive portions;
each of the first and second optical cavity parts including a respective container;
the first part'"'"'s container having at least one opening through which bodily fluid can transfer between the container'"'"'s interior and exterior when the product is implanted in a body;
the second part'"'"'s container being closed and containing a reference fluid.

Abstract
An implantable product includes an optical cavity structure with first and second parts, each of which can operate as an optical cavity. The first part includes a container with at least one opening through which bodily fluid can transfer between the container'"'"'s interior and exterior when the product is implanted in a body. The second part includes a container that is closed and contains a reference fluid. The implantable product can also include one or both of a light source component and a photosensing component. Photosensed quantities from the first part'"'"'s output light can be adjusted based on photosensed quantities from the second part'"'"'s output light. Both parts can have their light interface surfaces aligned so that they both receive input light from a light source component and both provide output light to a photosensing component.
