Employing 8-bit 65GSps digital-to-analog converters with pre-equalization and Nyquist pulse-shaping, we generated a terabit superchannel based on both low-baud-rate Nyquist frequency-division-multiplexing (FDM) dual polarization quadrature-phase-shift-keying (DP-QPSK) and high-baud-rate Nyquist DP-QPSK signals. The 1.2-Tb/s superchannel transmission over 80100 km ultra-large-area fiber with...
The influence of focal length on optical limiting power characteristics based on stimulated Brillouin scattering in CCl4 medium is investigated numerically and experimentally. The simulation results show that, the characteristics of limiting power and pulse shape are controlled mainly by focal length when other parameters are fixed. When focal length is short, for example 5 cm, the characteristic...
A simple refractive-index fiber sensor based on a tilted Bragg fiber grating interacting with multimode fiber is described. The sensor structure is formed by insertion of a small section of MMF between the single-mode fiber and the tilted Bragg fiber grating. The average reflective power in the cladding modes of the TFBG reflected a different power as the surrounding refractive index changes, while...
