The transverse asymmetry of the index modulation profile in the asymmetric few-mode fiber Bragg grating (FM-FBG) was investigated. The transverse asymmetry of the index modulation profile will lead to mode conversion between modes with the different

We propose and demonstrate a narrow-bandwidth few-mode Fabry-Perot (FP) filter based on the tilted fiber Bragg gratings (TFBGs). The proposed filter is based on the few mode fiber which possesses ring-core structure. The two TFBGs function as the ref

We investigate the inter-mode forward stimulated Brillouin scattering (FSBS) in nanofibers in this article. An extraordinary high Brillouin peak value is predicted for the interaction between the HE11 and the high-order optical mode (TE01). The corre

We experimentally demonstrate a multi-wavelength fiber laser based on dual-Sagnac comb filter with LP11 modes output. The filter is used to generate comb spectrum, which is consisted of three optical couplers, two polarization controllers and two seg

We experimentally demonstrated a method of generating continuously wavelength-switchable LP11 mode in an all-fiber laser. A Mach–Zehnder filter is constructed to provide a comb spectrum. A fused mode selective coupler (MSC) is used to obtain mode c

We propose a few-mode erbium-ring-doped fiber laser with high slope efficiency towards an individual transverse vector mode output. Based on the rate equation, specific transverse vector mode output is achieved through numerical investigations of the

During the stimulated Brillouin scattering (SBS) process, when the two H E 11 modes in the pump light and scattered light have different polarization states, between which is an angle θ , the Brillouin gain spectrum characteristics in a microfiber a

We present the characteristics of intra-mode forward stimulated Brillouin scattering (FSBS) induced by HE11 and high-order optical mode (HOM) in nanofibers, respectively. Multiple transverse acoustic modes (TAMs) would be excited in the FSBS process.
