TL;DR: In this paper, a novel polarization-dependent no core single mode-no core (NSN) fiber structure for twist and temperature sensing has been experimentally investigated, which involves a section of polarization maintain fiber sandwiched into NSN fiber structure, only using the splicing method.

TL;DR: A ring cavity erbium-doped fiber laser based on asymmetric structure filter with two polarization-maintaining fiber Bragg grating (PMFBG) Fabry-Perot cavities is proposed and demonstrated for switchable dual-wavelength single-polarization single-longitudinal-mode (SLM) operation as mentioned in this paper.

TL;DR: The results show that when the increasing of the cavity length of a single-cavity Fabry-Perot (FP) structure results in multiple resonant peaks in the stop band, the two-c Cavity FP structures of the same length can inhibit the secondary resonant Peaks and keep the main peak without degrading the performance through appropriately designing the cavity lengths and FBGs.

TL;DR: In this article, a U-shaped tunnel connected side coupled nanoring resonator waveguide system is proposed to generate Fano interference in a novel mechanism by mutually coupling the infrared light through the artificially introduced U-tunnel to two nanorings with the same resonant wavelength, single symmetric Lorentzian resonance transforms to asymmetric Fano resonance within the original resonant spectral range.

TL;DR: Based on numerical simulations, the performance of the cantilever structure as a PMD compensator is assessed for 10-Gbits/s nonreturn-to-zero transmission systems with a large DGD.
