ABSTRACT

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 space–for photonic systems. A number of techniques have been developed over the years, generically referred to as Shortcuts to Adiabaticity, that promise to speed up the evolution of the process without compromising performance. Here we review and compare these techniques, and evaluate their performance using full numerical simulations of realistic two-waveguide couplers, which perform a key function in photonic circuits.

波导耦合器绝热的捷径-理论与实现

摘要

绝热过程在物理学和工程学中无处不在。这种过程的一个缺点是，对于原子系统，例如在时间上，对于光子系统，在空间上，它们往往很慢。多年来，已经开发了许多技术，通常称为绝热捷径，有望在不影响性能的情况下加快工艺的发展。在这里，我们回顾和比较这些技术，并使用真实的两波导耦合器的完整数值模拟来评估其性能，该耦合器在光子电路中起关键作用。
