Abstract
An optical sensor () comprises an optical cavity defined by a dielectric body and responsive to one or more physical environmental conditions, and a waveguide () having a terminal end spaced apart from the optical cavity such that light is optically coupled from the terminal end of the waveguide () to the optical cavity. The waveguide () is arranged such that, in use, it is maintained at a first temperature that would not damage the optical coupling to the optical cavity when the dielectric body is maintained at a second temperature sufficient to damage the optical coupling to the optical cavity.
