Exciton-polariton emission from organic semiconductor optical waveguides [PDF]
, 2011 We photo-excite slab polymer waveguides doped with J-aggregating dye molecules and measure the leaky emission from strongly coupled waveguide exciton polariton modes at room temperature. We show that the momentum of the waveguide exciton polaritons can be controlled by modifying the thickness of the excitonic waveguide.

Nanoscale waveguiding methods [PDF]
Nanoscale Research Letters, 2007 While 32 nm lithography technology is on the horizon for integrated circuit (IC) fabrication, matching the pace for miniaturization with optics has been hampered by the diffraction limit. However, development of nanoscale components and guiding methods is burgeoning through advances in fabrication techniques and materials processing.

Advanced Engineering Materials, EarlyView.This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

TE/TM-Pass Polarizer Based on Lithium Niobate on Insulator Ridge Waveguide
IEEE Photonics Journal, 2013 We propose a TE/TM-pass polarizer based on a shallow X-cut lithium niobate-on-insulator (LNOI) ridge waveguide. In shallow X-cut LNOI ridge waveguides, the leaky mode is interchanged between TE and TM polarization waves depending on the ridge waveguide ...

Chiral Waveguides for Robust Waveguiding at the Deep Subwavelength Scale [PDF]
Physical Review Applied, 2018 Guiding waves at scales shorter than the wavelength is crucial for many applications, including compact signal-processing systems and concentration of wave energy. High sensitivity to geometrical imperfections and disorder-induced backscattering, however, pose major problems. This study proposes using a chiral metamaterial, in which the waves guided at

Perfectly Conducting Graphene Electronic Waveguide with Curved Channels [PDF]
, 2017 We theoretically investigate the electronic transport properties of curved graphene waveguides by employing non-equilibrium Green's function techniques. We systematically study the dependence of the confined waveguide modes on the potential difference, the width of waveguide and side barrier.
