Novel method for measuring nonlinear coefficient in optical fibers based on phase mismatching four-wave-mixing is proposed. With simple setup, we demonstrate measurements for both high nonlinearity dispersion-shifted fiber and low nonlinearity standard SMF.
We experimentally demonstrate all-optical network coding by showing cascaded operation of optical XOR gates. The gate consists of an integrated Mach-Zehnder interferometer which branches contain semiconductor optical amplifier based wavelength converters.
We propose a novel all-optical modulation format conversion scheme from on-off-keying to 16 quadrature amplitude modulation using nonlinear optical loop mirror based on parametric amplification and cross-phase modulation in optical fibers.
We experimentally investigate a dispersion tolerance of transmitted OOK signal for all-optical OOK/BPSK modulation format conversion using cross-phase modulation in optical fiber.
We propose and demonstrate an all-optical XOR logic gate accompanied with modulation format conversion from non-return-to-zero on-off-keying to return-to-zero binary phase-shift-keying by the use of cross-phase modulation in optical fiber.
We demonstrate an all-optical modulation format conversion from non-return-to-zero on-off-keying to return-to-zero multilevel amplitude-phase-shift-keying based on parametric amplification and cross-phase modulation in optical fibers.
We demonstrate an error-free all-optical 2times10.7 Gb/s NRZ-OOK to 10.7 Gsymbol/s RZ-QPSK modulation format conversion using a newly developed integrated SOA three-arm-MZI wavelength converter module.
