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 cubic, tetragonal, and orthorhombic phase of potassium niobate (KNbO3)
are studied based on density-functional theory. Starting from the relaxed atomic
geometries, we analyze the influence of self-energy corrections on the electronic
band structure within the GW approximation. We find that quasiparticle shifts
widen the direct (indirect) band gap by 1.21 (1.44), 1.58 (1.55), and 1.67 (1.64)
eV for the cubic, tetragonal, and orthorhombic phase, respectively. By solving
the Bethe-Salpeter equation, we obtain the linear dielectric function with excitonic
and local-field effects, which turn out to be essential for good agreement with
experimental data. From our results, we extract an exciton binding energy of 0.6,
0.5, and 0.5 eV for the cubic, tetragonal, and orthorhombic phase, respectively.
Furthermore, we investigate the nonlinear second-harmonic generation (SHG) both
theoretically and experimentally. The frequency-dependent second-order polarization
tensor of orthorhombic KNbO3 is measured for incoming photon energies between
1.2 and 1.6 eV. In addition, calculations within the independent-(quasi)particle
approximation are performed for the tetragonal and orthorhombic phase. The novel
experimental data are in excellent agreement with the quasiparticle calculations
and resolve persistent discrepancies between earlier experimental measurements
and ab initio results reported in the literature.

text: 'The KTiOPO4 (KTP) band structure and dielectric function are calculated on
various levels of theory starting from density-functional calculations. Within
the independent-particle approximation an electronic transport gap of 2.97 eV
is obtained that widens to about 5.23 eV when quasiparticle effects are included
using the GW approximation. The optical response is shown to be strongly anisotropic
due to (i) the slight asymmetry of the TiO6 octahedra in the (001) plane and (ii)
their anisotropic distribution along the [001] and [100] directions. In addition,
excitonic effects are very important: The solution of the Bethe–Salpeter equation
indicates exciton binding energies of the order of 1.5 eV. Calculations that include
both quasiparticle and excitonic effects are in good agreement with the measured
reflectivity.'

text: "Measurement-induced nonclassical effects in a two-mode interferometer are\r\ninvestigated
theoretically using numerical simulations and analytical results.\r\nWe demonstrate
that for certain parameters measurements within the\r\ninterferometer lead to
the occurrence of two-mode squeezing. The results\r\nstrongly depend on the detection
probability, the phase inside the\r\ninterferometer, and the choice of the input
states. The appropriate parameters\r\nfor maximized squeezing are obtained. We
analyze the influence of losses and\r\nconfirm that the predicted effects are
within reach of current experimental\r\ntechniques."

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.
