Key Points

Mid-infrared Goos–Hänchen shifts were significantly enhanced via resonant optical tunneling in graphene stacks, with implications for optical technologies.
The enhancement was shown to be order-of-magnitude through critical coupling in the transverse magnetic channel.
The study utilized a resonant optical tunneling approach, focusing on how critical coupling affects optical shifts in materials.
This work highlights new potential for mid-infrared applications, emphasizing the need for further exploration in advanced optical systems.

Implication

This analysis demonstrates enhanced mid-infrared Goos–Hänchen shifts in graphene, suggesting new optical applications.

Abstract

{We demonstrate a mid-infrared (mid-IR) resonant optical tunneling platform that yields order-of-magnitude enhancement of the Goos--H\"anchen (GH) shift through critical coupling in the transverse magnetic (TM) channel. The device comprises...
