Role of photonic bandgap in transverse localization of light in a disordered waveguide lattice
Role of photonic bandgap transverse localization of light disordered waveguide lattice Optics
2012/4/24
The role of a prominent photonic bandgap (PBG) on the phenomenon of transverse localization of light in an evanescently coupled disordered one-dimensional semi-infinite lossless waveguide lattice has ...
Role of Azimuthal Energy Flows in the Geometric Spin Hall Effect of Light
Light beam Circular polarization Oblique incidence Lateral shift Transverse energy flow Angular momentum
2011/8/29
In an oblique section of a paraxial beam with angular momentum, the beam center of gravity (CG) is shifted with respect to its position in the normal cross section. We relate this shift with the inter...
Optically induced spin polarisation of the NV- centre in diamond: role of electron-vibration interaction
Optically induced spin polarisation NV- centre in diamond: role electron-vibration interaction
2010/11/22
The novel aspect of the centre (NV−) in diamond is the high degree of spin polarisation achieved through optical illumination. In this paper it is shown that the spin polarisation occurs as a co...
