[EN] We review the introduction of the space dimension into fiber-based technologies to
implement compact and versatile signal processing solutions for microwave and millimeter wave
signals. Built upon multicore fiber ...
[EN] We demonstrate experimentally an indexvariable optical true time delay (OTTDL) based on an array of
forty subwavelength grating (SWG) waveguides on silicon-oninsulator (SOI). Using the measured data and numerical
simulations, ...
[EN] Parity-time (PT) symmetry is an active research area that provides a variety of new opportunities for different systems with novel functionalities. For instance, PT symmetry has been used in lasers and optoelectronic ...
