We propose short and robust directional couplers designed by shortcuts to adiabaticity,
based on Lewis-Riesenfeld invariant theory. The design of directional couplers is discussed …

We design and fabricate a series of broadband silicon arbitrary power splitters with various

We propose a directional coupler exploiting the framework of adiabatic passage for two-

We propose a compact and high conversion efficiency asymmetric Y junction mode
multiplexer/demultiplexer for applications in on-chip mode-division multiplexing …

In this paper, we propose the use of the invariant based shortcuts to adiabaticity for the
analysis of directional couplers. By describing the dynamical evolution of the system using …

Shortcuts to adiabaticity, originally developed in the context of quantum control, are powerful
tools for the design of high coupling efficiency, robust, and short coupled-waveguide …

In this article we use the method of shortcuts to adiabaticity to design a photonic lattice (array
of waveguides) which can drive the input light to a controlled location at the output. The …

We report the first demonstration of broadband adiabatic directional couplers in thin-film
lithium niobate on insulator (LNOI) waveguides. A three LN-waveguide configuration with …
