Wideband operation of Mach-Zehnder interferomertic magneto-optical isolator using phase adjustment

All-optical switching using nonlinear subwavelength Mach-Zehnder on silicon.

We report on the experimental demonstration of ultrafast all-optical switching and wavelength down-conversion based on a novel nonlinear Mach-Zehnder interferometer with subwavelength grating and wire waveguides. Unlike other periodic waveguides such as line-defects in a 2D photonic crystal lattice, a subwavelength grating waveguide confines the light as a conventional index-guided structure an...

Tunable fractional-order differentiator using an electrically tuned silicon-on-isolator Mach-Zehnder interferometer.

We propose and experimentally demonstrate a tunable fractional order photonic differentiator using an on-chip electrically tuned Mach-Zehnder interferometer (MZI) structure. The phase shift at the resonant frequency of the MZI varies when applying different voltages, which can implement the fractional differentiation. Due to the large 3-dB bandwidth of the MZI, the differentiator is expected to...

Semiconductor-Optical-Amplifier Mach-Zehnder Interferometer Based Optical Networks

In this paper, an all-optical AND logic scheme which exploits the cross-phase modulation (XPM) effect in semiconductor-optical-amplifier-assisted Mach-Zehnder Interferometer (SOA-MZI), is proposed, performance analyzed and parameters optimized. The proposal is validated and the system performance under various parameters is examined through numerical simulations. With only moderate parameters, ...
