摘要

Abstract

3-dB couplers

which are commonly used in photonic integrated circuits for on-chip information processing

precision measurement

and quantum computing

face challenges in achieving robust performance due to their limited 3-dB bandwidths and sensitivity to fabrication errors. To address this

we introduce topological physics to nanophotonics

developing a framework for topological 3-dB couplers. These couplers exhibit broad working wavelength range and robustness against fabrication dimensional errors. By leveraging valley-Hall topology and mirror symmetry

the photonic-crystal-slab couplers achieve ideal 3-dB splitting characterized by a wavelength-insensitive scattering matrix. Tolerance analysis confirms the superiority on broad bandwidth of 48 nm and robust splitting against dimensional errors of 20 nm. We further propose a topological interferometer for on-chip distance measurement

which also exhibits robustness against dimensional errors. This extension of topological principles to the fields of interferometers

may open up new possibilities for constructing robust wavelength division multiplexing

temperature-drift-insensitive sensing

and optical coherence tomography applications.
