Efficient Two Photon Generation from an Emitter in a Cavity
M. I. Mazhari, Rituraj
Two-photon states are essential for fundamental applications in quantum information. One of the primary methods of two-photon generation is based on parametric down-conversion, but…
Wavelength-Agnostic Metasurface Design for Next-Generation 2D Photodetectors
Ayush M. Jamdar, Rituraj, Srini Krishnamurthy +2
We explore a versatile technique for inverse designing 2D photonic crystal metasurfaces. These surfaces, known for their ability to manipulate light-matter interactions, can be pre…
New design paradigm for highly efficient and low noise photodetector
Sagar Chowdhury, Rituraj, Srini Krishnamurthy +1
Achieving high quantum efficiency (QE) with low dark count is essential for highly sensitive photodetectors (PDs), including single photon avalanche detectors (SPADs). However, hig…
Highly sensitive and efficient 1550 nm photodetector for room temperature operation
Rituraj, Zhi Gang Yu, R. M. E. B. Kandegedara +2
Photonic quantum technologies such as effective quantum communication require room temperature (RT) operating single- or few- photon sensors with high external quantum efficiency (…
Detecting the relative phase between different frequency components of a photon using a three-level atom coupled to a waveguide
Janet Zhong, Rituraj, Fatih Dinc +1
We study the scattering of a single photon propagating along a waveguide in an arbitrary superposition state two frequencies with a single three-level atom in a superposition o…
Parametric Mie resonances and directional amplification in time-modulated scatterers
V. Asadchy, A. G. Lamprianidis, G. Ptitcyn +7
We provide a theoretical description of light scattering by a spherical particle whose permittivity is modulated in time at twice the frequency of the incident light. Such a partic…
