Simultaneous Measurement Of Gas Pressure And Temperature Using A Microbubble Resonator Combined With An Fbg, Ketan Dong, Ke Tian, Chuanzhen Zhao, Huibin Li, Jibo Yu, Angzhen Li, Xiaoling Sun, Elfed Lewis, Gerald Farrell, Pengfei Wang

Conference Papers

We propose and demonstrate a microbubble resonator combined with a fiber Bragg grating (FBG) for simultaneous measurement of gas pressure and temperature. The approach used allows for very close proximity (<200 >μm) between the FBG and the microbubble resonator. The microbubble resonator is fabricated in a section of hollow-core fiber (HCF), spliced to a single-mode fiber (SMF) with a pre-inscribed FBG to form a single-ended open structure. Fresnel reflection from the HCF cleaved end means that broadband light is reflected backwards in the same direction as the Bragg wavelength from the FBG. A tapered fiber couples the reflected broadband light …

Tunable Erbium-Doped Fiber Ring Laser With A Polymer Micro Bottle Resonator, Anuradha Rout, Zhe Wang, Zhuochen Wang, Yuliya Semenova

Conference Papers

A new tunable fiber laser structure based on an erbium-doped fiber ring laser (FRL) and a polymer-based microbottle resonator (PMBR) as the wavelength selective filter is proposed and demonstrated. The tunability of the laser output in response to axial strain of up to 253.6 με applied to the PMBR is demonstrated experimentally. When the strain was applied to the PMBR’s long axis, the central lasing wavelength shifted towards shorter wavelengths in a linear fashion. The laser's strain sensitivity was determined to be 0.69 pm/με. The proposed strain-tunable PMBR laser offers the advantages of simple structure, low cost, robust performance, and …
