Electro-optic modulation in a sub-wavelength gap-plasmon guide
Subimal Deb, K. Sarat Kumar, P. Anantha Lakshmi +1
We show efficient electro-optic modulation in a subwavelength gap-plasmon waveguide (GPW) formed by an electro-optic polymer with metal coatings. The proposed device is studied in…
Signature of strong atom-cavity interaction on critical coupling
Shourya Dutta Gupta, Subimal Deb, S. Dutta Gupta
We study a critically coupled cavity doped with resonant atoms with metamaterial slabs as mirrors. We show how resonant atom-cavity interaction can lead to a splitting of the criti…
Competition between structural and intrinsic dispersion in delay through a left handed medium
Dheeraj Golla, Subimal Deb, S Dutta Gupta
We study resonant tunneling through a layered medium with a negative index medium (NIM) slab as a constituent layer. We demonstrate large delays in transmission mediated by the sur…
Critical coupling in a system of two coupled negative index medium layers
Subimal Deb, S. Dutta Gupta
We study critical coupling (CC) in a system of two coupled negative index medium (NIM) layers leading to near-total suppression of both reflection and transmission at specified fre…
