Radio-over-Fiber (RoF) techniques enable transmission of microwave and millimeter-wave signals for long distances with small loss. Due to the limited signal handling capabilities of electrical/optical ...
A CMOS-compatible athermal flat-topped silicon Mach-Zehnder filter is proposed and experimentally demonstrated using hybrid strip-slot waveguides. The measured temperature-dependent wavelength shift ...
A low-loss and low-crosstalk Mach-Zehnder mode/wavelength multi/demultiplexer based on silica-PLC platform is proposed for WDM/MDM transmission. The Mach-Zehnder filter for “mode” and “wavelength” can ...
We propose the technique of signal predistortion using a dual-drive Mach-Zehnder modulator and nonlinear digital filters, and demonstrate compensation of 13600 ps/nm, equivalent to 800 km of standard ...
A microring-assisted Mach-Zehnder interferometer has been studied. The structure demonstrates better extinction ratio, eye opening and bandwidth than a single microring modulator. The extinction of ...
A novel optical frequency-hopping (OFH) scheme using dual-drive Mach-Zehnder modulator (DD-MZM) is proposed and demonstrated for secure transmission in fiber-optic networks. In the proposed scheme, by ...
A novel and simple photonic approach for generating symmetry-tunable full-duty triangular-shaped microwave waveforms is proposed and experimentally demonstrated. In this approach, a simple commercial ...
We demonstrate an ultra-high efficiency III-V/Si metal-oxide-semiconductor capacitor Mach-Zehnder modulator with low temperature sensitivity. The measured modulation efficiencies of the fabricated ...
We demonstrate a vertical p-n junction silicon Mach-Zehnder modulator constructed with hydrogenated amorphous silicon strip-loaded waveguides on a flat SOI platform. A 3-mm-long phase shifter shows ...
Based on thin film lithium niobate platform, we experimentally demonstrate a high-performance ring-assisted Mach-Zehnder interferometer flat-top filter. It features a crosstalk lower than -25 dB, a ...
Based on a Silicon and Lithium Niobate hybrid integration platform, we demonstrate Mach-Zehnder modulators that feature low insertion loss, low drive voltage, large modulation bandwidth, high ...
