The Brillouin gain coefficient of a 1.16-m-long bismuth oxide-based photonic crystal fiber is measured by using a beat lock-in probe detection scheme to overcome the limitation caused by considerable pump beam back-reflection at splicing points. gB is found to be ~4times10-11 m/W.
We have fabricated Bi2O3-based microstructured fiber using a novel method. It was experimentally revealed that this fiber shows nonlinearlity ~ 780 W-1km-1 and GVD ~ -25 ps/nm/km simultaneously.
Optical time-division demultiplexing of 160-Gbit/s optical signals is demonstrated by using a 2-m-long dispersion-shifted Bi2O3-based photonic crystal fiber. Power penalties are less than 6 dB for all 10-Gbit/s tributaries.
We demonstrate an all fiber-based OTDM receiver incorporating clock recovery and demultiplexing functions using short lengths of bismuth oxide-based nonlinear fiber and erbium-doped bismuth oxide fiber. Error-free, overall operation is achieved at 80 Gbit/s and the clock recovery is also shown to be operable at 160 Gbit/s.
We investigate the feasibility of the use of 1-m length of our fabricated bismuth oxide-based nonlinear fiber (Bi-NLF) for the implementation of a Mamyshev-type 2R regenerator that is based on self-phase-modulation-induced spectral broadening followed by spectral filtering, and evaluate the regeneration performance in both experimental and theoretical ways from a perspective of system application...
We demonstrate the use of 1-m length of Bi2O3-based nonlinear fiber for implementing a 10-Gbit/s NRZ signal wavelength converter based on XPM-induced polarization rotation. No SBS suppression scheme was employed owing to a high SBS threshold of the fiber
