“…Based on the experimental findings, the broadest SC spectra were generated when the pump power was injected into the anomalous dispersion region. In this region, the soliton fission dynamics dominate the spectra evolution [18,29,30]. Hence, a broadly tunable soliton was obtained and the dispersive wave source was associated to the SC generation.…”

We propose and demonstrate the generation of a supercontinuum with a few-mode fiber. Due to the accommodation of a few-mode fiber in LP and LP modes, the system was engineered to detect the octave spanning supercontinuum in both modes. A mode-locked laser with . nm spectral bandwidth at a central wavelength of nm, . ps pulse width, . MHz repetition rate, and . dB peak-To-pedestal extinction ratio was implemented with a carbon nanotube saturable absorber. This mode-locked laser was employed as a seed laser for the consecutive generation of supercontinuum with a m few-mode fiber. The laser modes were adjusted with a mode filter to propagate in either LP or LP modes, which were accessed with a charge-coupled device camera. A fair comparison between a few-mode fiber and a single-mode fiber was made for supercontinuum generation in the LP mode.Despite the fact that the few-mode fiber has lower optical power than the single-mode fiber due to higher attenuation, this fiber provides flexible design of laser modes. This work demonstrates the first attempt to generate a supercontinuum with a few-mode fiber, whereby the broad tunable soliton and associated dispersive wave sources for both laser modes were comprehensively studied. © Astro Ltd.

Numerical investigation of a real-time temperature sensor based on high-order soliton compression

et al. 2021

Temperature sensors based on photonic crystal fibers (PCFs) have attracted considerable attentions due to their desirable advantages. However, the real-time temperature sensing in the temporal region is rarely studied. Here, an all-fiber real-time high-sensitivity temperature sensor is fabricated based on the high-order soliton compression process. A 1560 nm femtosecond fiber laser is used as the injected pulse source and the alcohol-filled silica PCF is adopted as the temperature sensitive device. Temperature sensing can be realized by detecting the peak values of temporal profiles with an oscilloscope at the change of temperature. The oscilloscope possesses faster response rate than the optical spectrum analyzer and can record the variation of the single pulse. Through numerical simulations, a real-time temperature sensor with the sensitivity of 4.91 W °C−1 is achieved at the fiber length of 21 cm. Our simulated results show that the designed temperature sensors with low cost, compact all-fiber structure and real-time response are competitive for application in temperature measurement devices.

“…High birefringence fibers are mostly developed using the silica material for optical communication application. For mid-infrared application much attention has been paid to soft glasses such as tellurite, chalcogenide and fluoride [8][9][10]. Among these, fluoride fiber (ZrF 4 -BaF 2 -LaF 3 -AlF 3 -NaF, ZBLAN) is considered to be the most stable and technological advance for high power applications [11].…”

A high birefringent and low confinement loss fluoride photonic crystal fiber (PCF) is proposed with two elliptical air holes in the cladding. The effective refractive index, birefringence, nonlinear coefficient and confinement loss are numerically simulated using the COMSOL Multiphysics software based on finite element method (FEM) with perfectly matched layer boundary (PML) condition. Its birefringence value reaches the magnitude of 1.636 × 10 −2 and confinement loss is 3.7 × 10 −2 dB/m at 2 μm wavelength.
