Room-Temperature Pressure-Induced Optically-Actuated Fabry-Perot Nanomechanical Resonator with Multilayer Graphene Diaphragm in Air
We demonstrated a miniature and in situ ~13-layer graphene nanomechanical resonator by utilizing a simple optical fiber Fabry-Perot (F-P) interferometric excitation and detection scheme. The graphene film was transferred onto the endface of a ferrule with a 125-μm inner diameter. In contrast to the pre-tension induced in membrane that increased quality (Q) factor to ~18.5 from ~3.23 at room tem...
متن کاملFabry-Perot diaphragm fiber-optic sensor.
The general theory of a diaphragm fiber-optic sensor (DFOS) is proposed. We use a critical test to determine if a DFOS is based on Fabry-Perot interference or intensity modulation. By use of the critical test, this is the first design, to the best of our knowledge, of a purely Fabry-Perot DFOS, fabricated with microelectromechanical system technology, and characterized as an audible microphone ...
متن کاملFabry-Perot Diaphragm Fiber Optic Sensor (DFOS) for Acoustic Detection
The diaphragm fiber optic sensor (DFOS) solely based on Fabry-Perot multiple beam interference has been designed and fabricated with Micro-electric mechanical system (MEMS) technology. The silicon diaphragm with an embossed center was designed with an interference gap width kept accurately. The DFOS is verified to be truly and purely of Fabry-Perot type via a critical test. Parallel testing of ...
متن کاملCenter embossed diaphragm design guidelines and Fabry-Perot diaphragm fiber optic sensor
This research established the design guidelines for center embossed diaphragms for micro-diaphragm fiber type sensors. Following the guidelines, a center embossed diaphragm fiber optic sensor (CE-DFOS) based on Fabry–Perot interference was designed and fabricated with micro-electro-mechanical system (MEMS) technology. The CE-DFOS was experimentally verified to have the designed intrinsic freque...
متن کاملFabry-Perot Sapphire Temperature Sensor for Use in Coal Gasification
Sapphire fiber based temperature sensors are exceptional in their ability to operate at temperatures above 1000oC and as high as 1800oC. Sapphire fiber technology is emerging and the fiber is available commercially. Sapphire fiber has a high loss, is highly multi-mode and does not have a solid cladding, but it is nonetheless very useful in high temperature applications. Of the available interfe...
