text: We show that narrow trenches in a high-contrast silicon-photonics slab can
act as lossless power dividers for semi-guided waves. Reflectance and transmittance
can be easily configured by selecting the trench width. At sufficiently high angles
of incidence, the devices are lossless, apart from material attenuation and scattering
due to surface roughness. We numerically simulate a series of devices within the
full 0-to-1-range of splitting ratios, for semi-guided plane wave incidence as
well as for excitation by focused Gaussian wave bundles. Straightforward cascading
of the trenches leads to concepts for 1×M-power dividers and a polarization beam
splitter.

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.
