Summary: The PCF sensor based on SPR technology has flexibility in various aspects but faces challenges in practical application, such as complex design and low sensitivity. To address these issues, a new structure with longer vertical distance between the D-shaped large air hole channel and the core is proposed, resulting in enhanced plasma mode and improved wavelength sensitivity. The combination of hexagonal double-clad air hole structure and D-type structure ensures a simple design and facilitates manufacturing, leading to greatly enhanced wavelength sensitivity and promising applications in high-sensitivity detection.

Summary: This study investigated the electrically sensing characteristics of a LC-infiltrated polarization-maintaining PCF and proposed a new method for fiber welding. The refractive-index distribution of the LC-infiltrated PCF varies with electric voltage, allowing for voltage detection with improved sensitivity as voltage increases. The Sagnac interferometer embedded with the LC-infiltrated PCF can function as a voltage sensor, electro-optical modulator, or filter.

Summary: This study demonstrates that a single supermode interferometer can monitor two parameters simultaneously by utilizing strongly coupled multicore fiber and standard single mode fiber. The reflection spectrum of the interferometer changes with refractive index and temperature, allowing for easy decoding of interference patterns in the Fourier domain. An important advantage of this device is that the length of the multicore fiber does not affect sensor performance, and the device can be reused multiple times.

Summary: The authors use femtosecond laser pulses to study the formation of diffraction patterns in hydrogen-bonded liquids, which can be used to identify the target liquid. The interaction between laser and liquid can cause temperature changes and alter the index of refraction, resulting in unique diffraction patterns. This noninvasive and simple technique may be useful for practical applications in developing compact thermal lens spectroscopic instruments.
