Continuous-wave four-wave mixing in a single-mode tellurite fiber

Abstract

Four-wave mixing in a 6 -m long single-mode tellurite (78TeO2-5Bi2O3-5ZnO-12Na2O, mol%, TBZN) fiber was experimentally observed with the continuous-wave (CW) pump wavelengths changing from ∼1530 to 1565 nm. Conversion efficiency of ∼−20 dB was obtained with the CW signal input power of ∼5 mW at the pump wavelength of ∼1565 nm. The optical signal gain in the TBZN tellurite fiber was numerically simulated, and the result agreed well with the experiment.

Flexible wavelength conversion based on four‐wave mixing in tellurite microstructured optical fibre

“…Our group has reported FWM‐based wavelength conversion based on a single mode tellurite fibre. However, it can only be operated in a 10 nm wavelength range near the pump wavelength, and the conversion efficiency is as low as −20 dB [9]. This is because the fibre's zero dispersion wavelength (ZDW) is far from the pump wavelength, and the signals are not located in the phase‐matched FWM parametric gain bands.…”

Highly efficient picosecond degenerate four-wave mixing in a tellurite microstructured optical fiber

“…16) 19) In a tellurite fiber, DFWM wavelength conversion with an efficiency of −20 dB has been demonstrated in a step-index fiber with the ZDW located around 1908 nm. 20) In these previous works, continuouswave (CW) laser modules in the C band were used as the pump source. By using a picosecond pulse train as the pump, DFWM-assisted supercontinuum generation has been observed in a birefringent tellurite fiber with ZDWs located at 1560 and 1532 nm.…”
