Polaritons in photonic hypercrystals of van der Waals materials
Nihar Ranjan Sahoo, Brijesh Kumar, S. S. Jatin Prasath +3
In-plane Hyperbolic Phonon polaritons (HPhPs) are quasiparticles formed via coupling of photons and optical phonons in in-plane hyperbolic materials and offer unique applications i…
An electroplating-based plasmonic platform for giant emission enhancement in monolayer semiconductors
Abhay Anand V S, Mihir Kumar Sahoo, Faiha Mujeeb +4
Two dimensional semiconductors have attracted considerable attention owing to their exceptional electronic and optical characteristics. However, their practical application has bee…
Electroplating based engineering of plasmonic nanorod metamaterials for biosensing applications
Mihir Kumar Sahoo, Abhay Anand VS, Anshuman Kumar
Sensing lower molecular weight in a diluted solution using a label-free biosensor is challenging and requires a miniaturized plasmonic structure, e.g., a vertical Au nanorod (AuNR)…
A low cost plasmonic platform for photon emission engineering of two dimensional semiconductors
Anuj Kumar Singh, Kishor K Mandal, Yashika Gupta +7
Although the field of 2D materials has democratized materials science by making high quality samples accessible cheaply, due to the atomically thin nature of these systems, an inte…
A photonic integrated chip platform for interlayer exciton valley routing
Kishor K Mandal, Yashika Gupta, Mandar Sohoni +2
Interlayer excitons in two dimensional semiconductor heterostructures show suppressed electron-hole overlap resulting in longer radiative lifetimes as compared to intralyer exciton…
Gate tunable light-matter interaction in natural biaxial hyperbolic van der Waals heterostructures
Aneesh Bapat, Saurabh Dixit, Yashika Gupta +2
The recent discovery of natural biaxial hyperbolicity in van der Waals crystals, such as -MoO, has opened up new avenues for mid-IR nanophotonics due to their deep subwavele…
