摘要:
The invention provides a miniature robust fiber optic pressure sensor. Theminiature fiber optic sensor comprises a Fabry-Perot chip bonded to an opticalfiber. The invention provides a new sensor design that reduces the amount ofadhesive required to bond the optical fiber to the Fabry-Perot sensor suchthat the sensor is less sensitive to moisture. The invention also providesmanufacturing methods of the sensor comprising a method based on etching and amethod based on using an excimer laser. The invention also provides a chipdesign that renders the chip less sensitive to thermal changes. The inventionalso provides a chip design in which a sensor diaphragm has a well-definedthickness. The invention also provides a chip design that protects the chipfrom etching.
