| titleOfInvention | A kind of microbubble cavity coupling CO2 sensor based on whispering gallery mode and its production method |
| abstract | The present application discloses a microbubble cavity-coupled CO 2 sensor based on a whispering gallery mode and a fabrication method thereof. After amplifying the optical signal emitted by the spontaneous emission light source and coupling it into the microbubble cavity through a fiber cone, the optical signal is coupled with the PHMB on the inner wall of the microbubble cavity. The solid film is coupled to form a coupled optical signal, and then, the coupled optical signal is coupled into the spectrometer through the fiber cone. Because the PHMB solid film reacts with CO 2 gas, the refractive index of the PHMB solid film changes, which makes the coupling received by the spectrometer. The spectral absorption peak corresponding to the optical signal is shifted in position, and then the corresponding CO 2 gas concentration is matched from the pre-established relational database to obtain the CO 2 gas concentration to be measured, which makes the detection very convenient and has high accuracy. , the sensor of this embodiment has a simple structure, a long service life, is not affected by temperature, reduces the manufacturing cost and volume, and facilitates the miniaturization of the sensor. |
