Abstract: A resonator device 10 is disclosed. The resonator device may be used in a transducer or a sensor such as a pressure, force or acceleration sensor. The resonator device comprises a resonator 20 provided on a diaphragm 30. A cap 40 is provided which may be fusion bonded to the diaphragm 30 to enclose the resonator 20 and form a hermetically sealed package 10. The resonator device is excited by applying electromagnetic stimulation, such as infra-red or optical stimulation, which may be from a laser via a fiber 50. The resonator device may be interrogated by applying an electromagnetic signal into the optical cavity formed between the resonator 20 and the inside surface of the cap 40 to derive a frequency change of the resonator. As the resonator device incorporates a hermetically sealed package and is stimulated by electromagnetic radiation, it is robust and able to operate in harsh environments.

Abstract: Aligning an optical fiber with an optical device, component or package such as an optical transducer or sensor is disclosed, A housing for an optical device is provided having a tapered surface to receive a correspondingly tapered portion of a ferrule in which a fiber is mounted. The tapered surfaces, which may for example be frusta-conical or conical, enable the optical device and ferrule to be quickly and precisely aligned. An optical device may be provided in a cavity which may be sealed by the mating tapered surfaces. The optical device may also be provided on a mounting bracket with flexible supports connected to the housing to accommodate thermal expansion of the housing and maintain alignment.
