Path-integral analysis of passive, graded-index waveguides applicable to integrated optics
… waveguide structures, such as tapered and coupled waveguides of a wide variety of geometries. Tapered and coupled graded-index waveguides are the building blocks of waveguide junctions and tapered couplers, and have been mainly studied in the past through numerical simulations. Closed form …

Design of a high index contrast arrayed waveguide grating
… the dispersive waveguide array consists of bent waveguides, the size of an AWG is limited by the light loss in the bends. In their current form, silica-based gratings are too large to be made cheaply or to use as an integrated component. The proposed solution is to redesign the AWG using high …

Photon Statistics in Disordered Lattices
… photonic lattice, an array of evanescently coupled waveguides, is illuminated with an extended coherent optical field, discrete speckle develops. Numerical simulations and analytical modeling reveal that discrete speckle shows a set of surprising features, that are qualitatively …

Characterisation of silicon photonics devices
… the characteristics of high index contrast waveguides as a building blocks that can be designed, fabricated and employed on devices in silicon photonics. Initially in this work, a fully vectorial H-field based finite element method has been used to obtain the modal characteristics of high …
