Quaternion Weyl Transform and some uniqueness results

Rupak Kumar Dalai, Somnath Ghosh, R. K. Srivastava

In this article, we study the boundedness and several properties of the quaternion Wigner transform. Using the quaternion Wigner transform as a tool, we define the quaternion Weyl…

Exploring Unconventional Features Of Light Dynamics In Aubrey-Andre-Harper Model Based Quasi-periodic Optical Lattices

Suman Dey, Nikhil Ranjan Das, Somnath Ghosh

We report an Aubrey-Andre-Harper (AAH) model based quasi-periodic lossless evanescently coupled waveguide lattice to study the unconventional physics of light localization. We pres…

Hosting exceptional points in 1D photonic bandgap waveguide for mode engineering

Sibnath Dey, Somnath Ghosh

We report a planar 1D photonic bandgap waveguide exhibiting four second-order exceptional points (EP2s). The interactions between the selective pairs of supported quasi-guided TE m…
