Shortcuts to adiabaticity (STA) are fast routes to the final results of slow, adiabatic changes
of the controlling parameters of a system. The shortcuts are designed by a set of analytical …

Adiabatic processes are ubiquitous in physics and engineering. A drawback of such
processes is that they tend to be slow, either in time–for atomic systems, for example–or in …

Optical phased arrays (OPAs) on integrated photonic platforms provide a low-cost chip-scale
solution for many applications. Despite the numerous demonstrations of OPA transmitters …

A short and broadband silicon asymmetric Y-junction two-mode (de) multiplexer is proposed
and simulated. An adiabaticity parameter suitable for high index-contrast silicon waveguides …

In recent years, the concept of shortcuts to adiabaticity (STA), originally developed for
speeding up slow adiabatic state evolution in quantum systems, has found numerous …

We propose an ultrashort and broadband silicon mode-conversion polarization splitter-
rotator (PSR) consisting of a taper and a Y-junction both designed by the fast quasiadiabatic …

We propose a fast quasiadiabatic approach to the design of optical waveguide devices. This
approach distributes the system adiabaticity homogeneously over the device length, thus …

In this work, we introduce quantum-mechanical adiabatic passage into the design of spatial
acoustic four-waveguide (WG) couplers. Thanks to the agreement in form between the …

By applying invariant-based inverse engineering in the small-oscillation regime, we design
the time dependence of the control parameters of an overhead crane (trolley displacement …

In this paper, optical simulation of double rapid adiabatic passage (RAP) is investigated in
three evanescently coupled waveguides with longitudinally varying detunings of the …
