In this study, we utilized a discrete point configuration method in conjunction with genetic algorithm (GA) and particle swarm optimization (PSO) to design broadband polarization-maintaining anti-resonant fibers (PM-ARFs). The resulting structure features a confinement loss (CL) below 0.17 dB/m, birefringence of approximately 8.2 × 10−5, and a polarization loss ratio (PLR) close to 297 at 1550 nm, providing a usable bandwidth of 340 nm across a range from 1.27 μm to 1.61 μm.

A fiber sensor with significantly enhanced temperature and strain sensitivities is proposed. This sensor, which comprises a fiber Sagnac interferometer (FSI) in parallel with an improved fiber modal interferometer (FMI), has been validated in experiments. The FSI consists of a section of polarization-maintaining fiber (PMF) and a ${2}\! \times \!{2}$ 3 dB optical coupler (OC), serving as the sensing interferometer.

1. IntroductionDue to China’s industrial and energy structure, the rapid economic growth has consumed a large amount of energy, which is also accompanied by high CO2 emissions. From 1990 to 2020, the share of global CO2 emissions in China increased from 10% to 30.7% [1]. On a per capita basis, China’s per capita carbon emissions exceeded the world average in 2010 and were around 6.4 tons per capita in 2020, ranking around 15th in the world [2].
