Guided Plasmon Modes of a Graphene-Coated Kerr Slab 

Hajian, Hodjat; Rukhlenko, Ivan D.; Leung, Pui Tak; Caglayan, Humeyra; Ozbay, Ekmel (SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2016)
We study analytically propagating surface plasmon modes of a Kerr slab sandwiched between two graphene layers. We show that some of the modes that propagate forward at low field intensities start propagating with negative ...

Coupling enhancement of split ring resonators on graphene 

Cakmakyapan, Semih; Caglayan, Humeyra; Ozbay, Ekmel (PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2014)
Metallic split ring resonator (SRR) structures are used in nanophotonics applications in order to localize and enhance incident electromagnetic field. Electrically controllable sheet carrier concentration of graphene ...

Enhanced tunability of V-shaped plasmonic structures using ionic liquid gating and graphene 

Ozdemir, Onur; Aygar, A. Melis; Balci, Osman; Kocabas, Coskun; Caglayan, Humeyra; Ozbay, Ekmel (PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2016)
Graphene is a strong candidate for active optoelectronic devices because of its electrostatically tunable optical response. Current substrate back-gating methods are unable to sustain high fields through graphene unless a ...

Enhanced transmission and beaming via a zero-index photonic crystal 

Hajian, Hodjat; Ozbay, Ekmel; Caglayan, Humeyra (AMER INST PHYSICS, 1305 WALT WHITMAN RD, STE 300, MELVILLE, NY 11747-4501 USA, 2016)
Certain types of photonic crystals with Dirac cones at the Gamma point of their band structure have a zero effective index of refraction at Dirac cone frequency. Here, by an appropriate design of the photonic structure, ...

Multiple slow waves and relevant transverse transmission and confinement in chirped photonic crystals 

Serebryannikov, Andriy E.; Cakmak, A. Ozgur; Colak, Evrim; Caglayan, Humeyra; Kurt, Hamza; Ozbay, Ekmel (OPTICAL SOC AMER, 2010 MASSACHUSETTS AVE NW, WASHINGTON, DC 20036 USA, 2014)
The dispersion properties of rod-type chirped photonic crystals (PhCs) and non-channeled transmission in the direction of the variation of structural parameters from one cell of such a PhC to another are studied. Two types ...

Role of epsilon-near-zero substrates in the optical response of plasmonic antennas 

Kim, Jongbum; Dutta, Aveek; Naik, Gururaj V.; Giles, Alexander J.; Bezares, Francisco J.; Ellis, Chase T.; Tischler, Joseph G.; Mahmoud, Ahmed M.; Caglayan, Humeyra; Glembocki, Orest J.; Kildishev, Alexander V.; Caldwell, Joshua D.; Boltasseva, Alexandra; Engheta, Nader (OPTICAL SOC AMER, 2010 MASSACHUSETTS AVE NW, WASHINGTON, DC 20036 USA, 2016)
Radiation patterns and the resonance wavelength of a plasmonic antenna are significantly influenced by its local environment, particularly its substrate. Here, we experimentally explore the role of dispersive substrates, ...
