Fabrication of microfiber loop resonator‐based comb filter

Abstract: Microfiber loop resonator (MLR) is fabricated by coiling of a microfiber, which was obtained by the fast stretching of a heated single mode fiber. The MLR is embedded in low refractive index material to keep the system robust. Two comb filters with a constant spacing of 0.16 nm and 0.71 nm are successfully achieved, which the extinction ratio can be adjusted by controlling the state of polarization of the input light. It was also found that the wavelength of each peak and the spacing remain unchanged regardles… Show more

“…In the region of coupling, the circular symmetry of the microfiber‐air system is broken, which results in polarization dependent coupling coefficients. The comb extinction ratio depends on the polarization azimuth of incoming radiation . Furthermore, although self‐polarization coupling will still dominate, the rotating OM cross section in this region will slightly couple the two orthogonal polarizations that would otherwise propagate independently.…”

“…It is of great significance to develop a multifunctional all-fiber laser with multiwavelength switching ability to improve the performance in ultrafast all-optical communication networks. Therefore, in-depth research on NbTe 2 SA-based passive mode-locked erbium-doped fiber lasers (PML-EDFLs) can not only further understand the ultrafast optoelectronic response characteristics of NbTe 2 nanosheets but also have great significance for the development of compact and high-performance multiwavelength mode-locked fiber lasers for practical optoelectronic engineering applications. To obtain multiwavelength soliton pulses simultaneously, a common method is to introduce optical filters into the laser cavity, such as the Lyot filter, sagnac loop filter, multimode interference filter, microring resonator, fiber grating, Fabry–Pérot filter, and Mach–Zender interference filter . The output of multiwavelength soliton pulses in the above schemes is closely related to the characteristics of the filters.…”
