摘要： Optical fiber sensors adapted to measure strain or pressure are disclosed. The optical fiber sensor has a lead-in optical fiber having an end surface at a forward end, and a first optical element having a body with an outer dimension, Do, a front end surface coupled to the lead-in optical fiber, a pedestal including a retracted surface that is spaced from the front end surface, the retracted surface at least partially defining an optical cavity, a gutter surrounding the pedestal, the gutter having a gutter depth defining an active region of length, L, the first optical element further exhibiting L/Do≧0.5. Also provided are systems including the optical fiber sensor, and methods for manufacturing and using the optical fiber sensor. Numerous other aspects are provided.

摘要： A Fabry-Perot optical sensor for sensing a parameter such as pressure or the like is provided. The sensor includes a lead optical fiber from the end of which projects a spacer having an end surface curving inwardly. A diaphragm extends across the forward end of the spacer. The diaphragm is flexible in response to the parameter to be measured and defines a forward reflector of the Fabry-Perot cavity within the optical sensor. A method for manufacturing such a sensor is also provided.

摘要： An optical sensor and a method of manufacturing such as sensor are provided. The sensor includes a lead optical fiber with a single piece optical element joined permanently joined to its forward end. The optical element defines a spacer with a cavity therein at one end, and a diaphragm at the opposite end. The diaphragm is flexible in response to a parameter and the sensor defines a sensing Fabry-Perot resonator.

摘要： Variants of a method for manufacturing a microlens of any desired shape at the extremity of a lead waveguide are provided. A lens element having a non-uniform radial etchability profile is provided at the extremity of the lead waveguide. Preferably, the etchability profile is determined by a non-uniform radial distribution of dopants in the lens element. A spacer may optionally be placed between the waveguide and the lens element. The lens element is then brought down to an appropriate length and etched to its final shape which is mainly determined by the dopant distribution. An optical coupling assembly having a non-uniform radial distribution of dopants therein is also provided.
