text: We investigate optical microresonators consisting of either one or two coupled
rectangular strips between upper and lower slab waveguides. The cavities are evanescently
excited under oblique angles by thin-film guided, in-plane unguided waves supported
by one of the slab waveguides. Beyond a specific incidence angle, losses are fully
suppressed. The interaction between the guided mode of the cavity-strip and the
incoming slab modes leads to resonant behavior for specific incidence angles and
gaps. For a single cavity, at resonance, the input power is equally split among
each of the four output ports, while for two cavities an add-drop filter can be
realized that, at resonance, routes the incoming power completely to the forward
drop waveguide via the cavity. For both applications, the strength of the interaction
is controlled by the gaps between cavities and waveguides.

text: The invention relates to an optical junction between two optical planar waveguides.
For this purpose, an arrangement is provided of a first optical layer waveguide
(2) and a second optical slab waveguide (3), wherein the first optical layer waveguide
(2) and the second optical slab waveguide (3) different from each other is constant
over their respective length of thicknesses (d, r ) which the first optical layer
waveguide (2) with the second optical film waveguide (3) (by means of an optical
layer waveguide structure 4) is connected, which (along their entire length w)
has a thickness (h) which is between the thickness (d) the first optical waveguide
layer (2) and the thickness (r) of the second optical waveguide layer (3). According
to the invention, the thickness (h) of the optical layer waveguide structure (4)
over the entire length (w) of the optical layer waveguide structure (4) constant.
Thus, a possibility for an efficient and entailing low loss transition between
two optical planar waveguides is provided with different thickness.

text: Oblique propagation of semi-guided waves across slab waveguide structures
with bent corners is investigated. A critical angle can be defined beyond which
all radiation losses are suppressed. Additionally an increase of the curvature
radius of the bends also leads to low-loss configurations for incidence angles
below that critical angle. A combination of two bent corner systems represents
a step-like structure, behaving like a Fabry-Perot interferometer, with two partial
reflectors separated by the vertical height between the horizontal slabs. We numerically
analyse typical high-index-contrast Si/SiO2 structures for their reflectance and
transmittance properties. When increasing the curvature radius the resonant effect
becomes less relevant such that full transmittance is reached with less critical
conditions on the vertical distance or the incidence angle. For practical interest
3-D problems are considered, where the structures are excited by the fundamental
mode of a wide, shallow rib waveguide. High transmittance levels can be observed
also for these 3-D configurations depending on the width of the rib.

text: Semi-guided waves confined in dielectric slab waveguides are being considered
for oblique angles of propagation. If the waves encounter a linear discontinuity
of (mostly) arbitrary shape and extension, a variant of Snell's law applies, separately
for each pair of incoming and outgoing modes. Depending on the effective indices
involved, and on the angle of incidence, power transfer to specific outgoing waves
can be allowed or forbidden. In particular, critical angles of incidence can be
identified, beyond which any power transfer to non-guided waves is forbidden,
i.e. all radiative losses are suppressed. In that case the input power is carried
away from the discontinuity exclusively by reflected semi-guided waves in the
input slab, or by semi-guided waves that are transmitted into other outgoing slab
waveguides. Vectorial equations on a 2-D cross sectional domain apply. These are
formally identical to the equations that govern the eigenmodes of 3-D channel
waveguides. Here, however, these need to be solved not as an eigenvalue problem,
but as an inhomogeneous problem with a right-hand-side that is given by the incoming
semi-guided wave, and subject to transparent boundary conditions. The equations
resemble a standard 2-D Helmholtz problem, with an effective permittivity in place
of the actual relative permittivity. Depending on the properties of the incoming
wave, including the angle of incidence, this effective permittivity can become
locally negative, causing the suppression of propagating outgoing waves. A series
of high-contrast example configurations are discussed, where these effects lead
to - in some respects - quite surprising transmission characteristics.

text: Metal nanoparticles host localized plasmon excitations that allow the manipulation
of optical fields at the nanoscale. Despite the availability of several techniques
for imaging plasmons, direct access into the symmetries of these excitations remains
elusive, thus hindering progress in the development of applications. Here, we
present a combination of angle-, polarization-, and space-resolved cathodoluminescence
spectroscopy methods to selectively access the symmetry and degeneracy of plasmonic
states in lithographically fabricated gold nanoprisms. We experimentally reveal
and spatially map degenerate states of multipole plasmon modes with nanometer
spatial resolution and further provide recipes for resolving optically dark and
out-of-plane modes. Full-wave simulations in conjunction with a simple tight-binding
model explain the complex plasmon structure in these particles and reveal intriguing
mode-symmetry phenomena. Our approach introduces systematics for a comprehensive
symmetry characterization of plasmonic states in high-symmetry nanostructures.
