Apodized photonic crystals: A non-dissipative system hosting multiple exceptional points
Abhishek Mondal, Shailja Sharma, Ritwick Das
Optical systems obeying non-Hermitian dynamics have been the subject of intense and concerted investigation over the last two decades owing to their broad implications in photonics…
Impact of Pauli-blocking effect on optical limiting properties of WSe2 thin films
Km. Surbhi, Sourav Bhakta, Anupa Kumari +3
We present a detailed investigation on thickness-dependent third-order (\c{hi}^(3)) nonlinear optical properties of RF-sputtered WSe2 thin-films using ultrashort pulses centered at…
Geometric representation of adiabatic distributed-Bragg-reflectors and broadening the photonic bandgap
Shailja Sharma, Abhishek Mondal, Ritwick Das
Adiabatic following has been an widely-employed technique for achieving near-complete population transfer in a `two-level' quantum mechanical system. The theoretical basis, however…
Infrared rainbow trapping via optical Tamm modes in one-dimensional dielectric chirped photonic crystals
Shailja Sharma, Abhishek Mondal, Ritwick Das
The phenomenon of trapping broad spectrum of light is known as `rainbow trapping' and achieved using all-dielectric, hybrid metallo-dielectric or all-metallic configurations. In th…
Broadening the photonic bandgap in adiabatic distributed-Bragg-reflectors
Shailja Sharma, Abhishek Mondal, Ritwick Das
Adiabatic following has been an widely-employed technique for achieving near-complete population transfer in a two-level quantum mechanical system. The theoretical basis, however,…
Multiple reflection assisted Laser Doppler Vibrometer setup for high resolution displacement measurement
Nikhil Kumar Pachisia, Kajal Tiwari, Ritwick Das
Non-intrusive displacement measurement technique has a distinct edge over displacement sensors working in contact mode. Laser Doppler Vibrometry based schemes (LDV) offer such an a…
