Projectdetails

Introduction

Van der Waals (vdW) materials are ideal platforms to host light at the nanoscale (nanolight) with unprecedented properties such as strong in-plane anisotropy, arbitrarily large momenta, and high density of optical states. This opens the door to develop planar optical nanodevices compatible with current on-chip technologies.

Anisotropic Propagation

Remarkably, the in-plane anisotropic propagation of nanolight can be steered by stacking two slabs of a vdW material rotated with respect to each other. This results, for example, in canalization along one specific direction.

Project Aim

Inspired by this breakthrough in nano-optics, which extends the exciting prospects of twistronics to the optics realm, this ERC project aims to develop the field of Twistoptics. In Twistoptics, stacks of twisted layers of vdW materials enable unprecedented active control of light and light-matter interactions at the nanoscale.

Research Stages

Stage 1

In the first stage, we will carry out a study of the most fundamental optical phenomena in Twistoptics, including:

  1. Reflection of nanolight in twisted vdW structures
  2. Refraction of nanolight in twisted vdW structures

We will also develop a technological platform that will enable active manipulation of nanolight via strain fields.

Stage 2

In the second stage, we will utilize this knowledge and technological capabilities to design and fabricate functional nanodevices. The focus will be on exploring:

  1. Directional strong coupling between nanolight and molecular vibrations
  2. Inter-subband transitions in 2D semiconductors

This will contribute to the development of quantum Twistoptics.

Expected Outcomes

This proposal envisions the modification of material properties and dynamics at the nanoscale, leading to the realization of efficient and compact sources of IR radiation and polaritons that operate at room temperature.

Broader Impact

These fundamental scientific advances will be of enormous relevance for the development of new nanotechnologies, which will have a broad impact in various fields, such as:

  • Molecular nano-sensing
  • Quantum nanosciences
  • Nano-chemistry

In these areas, active control of fundamental light-matter processes at the nanoscale is of vital importance.
