Cascaded stimulated polariton scattering in a dual-Stokes cavity terahertz parametric oscillator

|

| Optica Verified
Terahertz polariton sources based on the stimulated polariton scattering (SPS) can generate the terahertz wave with a narrow linewidth and continuous tunability. A single SPS process has limited conversion efficiency due to the Manley–Rowe relation. In this Letter, we implement a dual-Stokes cavity structure within an intracavity terahertz parametric oscillator (TPO) to achieve a two-order cascaded SPS process.

| Optica Verified
Abstract In this work, the fabrication method of a U-shaped optical fiber (UOF) structure using single-mode fiber is proposed. Few UOF sensors have been developed to date, but the fabrication process has not been described in detail. Here, its subsequent homemade fabrication, optimization strategies, and analysis are thoroughly explored. Further, the influence of transmission on U-shaped diameter is explored. The transmitted intensity is mainly used to assess the strength of the evanescent field.

Abstract In this work, the fabrication and sensing performance of fusion structures based on single-mode fiber (SMF) and multimode fiber (MMF) with different cladding diameters are discussed, and the effects of different lengths of MMF and fiber etching on sensing performance are analyzed. First, the transmitted intensity measurement experiment is performed, and the results indicate that the performance of the SMF-MMF-SMF(SMS)-based structure is better for sensing purposes.
