Controlling Quantum Light in Ultra‑Thin Materials
This project explores how we can use tiny mechanical forces to control light at the quantum level in ultra-thin materials only a few atoms thick. By gently stretching these materials in precise ways, we can create and control quantum light sources - single‑photon emitters, which are important building blocks for future quantum communication and computing technologies.
Guiding and Controlling Excitons in 2D Material Heterostructures
This research studies how special light‑generated particles called excitons move, interact, and sometimes form exotic quantum states in layered two‑dimensional materials. By applying controlled mechanical strain, we investigate how these particles can be guided like water flowing down a slope, how they may group into quantum condensates, and how the light they emit can be directed for highly efficient future photonic and quantum devices.
Transparent Ceramic Materials for Next‑Generation Laser Systems
This project focuses on developing advanced transparent ceramic materials that can serve as powerful and cost‑effective alternatives to traditional crystal‑based lasers. By engineering high‑quality ruby and cobalt‑doped ceramic materials, we aim to create efficient lasers that operate in both visible and infrared ranges, enabling compact, robust, and high‑performance laser technologies for scientific, industrial, and defense applications.
Understanding Exciton-Phonon Interactions in Strained 2D Materials
This research explores how stretching and bending ultra‑thin two‑dimensional materials changes the way excitons in 2D materials heterostructures interact with phonons. The heterostructures are fabricated with exact twist angle between the layers. Using powerful tools such as Raman spectroscopy and photoluminescence, we study how strain affects different light‑emitting processes and quantum effects. This work provides new insights that are essential for designing future optical, sensing, and quantum devices
