Deterministic Single-Photon Emitter Arrays in Hexagonal Boron Nitride by Carbon-Assisted Focused Ion Beam Engineering
Mangababu Akkanaboina, Rohit Kumar, Brijesh Kumar +4
The realization of on-chip photonic circuits requires scalable and deterministic single-photon emitters (SPEs) at room temperature, which remain a challenge in van der Waals materi…
Active Control of Topological Exceptional Points in Non-Hermitian Metasurfaces
Parul Sharma, Sobhan Subhra Mishra, Yash Gupta +4
Active control and ultrafast switching of non-Hermitian photonic systems are essential for next-generation reconfigurable optical technologies. Here, we demonstrate dynamic tempora…
From Atomic Defects to Integrated Photonics: A Perspective on Solid-State Quantum Light Sources
Anuj Kumar Singh, Parul Sharma, Kishor Kumar Mandal +2
Single-photon emitters (SPEs) constitute a foundational resource for quantum technologies, including secure communication, photonic quantum computing, and emerging quantum network…
Protected Ion Beam Fabrication of Two-Dimensional Transition Metal Dichalcogenides based Photonic Devices
Lekshmi Eswaramoorthy, Parul Sharma, Brijesh Kumar +4
Two-dimensional (2D) transition metal dichalcogenides are pivotal for next-generation photonic devices due to their exceptional optical properties and strong light-matter interacti…
Sensing with Broken Symmetry: Revisiting Bound States in the Continuum
Brijesh Kumar, Elizaveta Tsiplakova, Samuel John +6
Metasurface with bound states in the continuum (BICs) offer exceptional potential for optical sensing due to their inherently high quality (Q) factors. However, the detection of sy…
