Polarization-Insensitive Widely Tunable Wavelength Conversion Based on Four-Wave Mixing Using Dispersion-Flattened High-Nonlinearity Photonic Crystal Fiber with Residual Birefringence

摘要

We demonstrate a simple polarization-insensitive scheme in a FWM-based wavelength converter using only a short span of high-nonlinearity dispersion-flattened PCF with residual birefringence with over 32 nm of tuning and 0.9-dB polarization sensitivity.
