Integrated Optoelectronics pp Cite as. Strip waveguides are planar waveguides with additional lateral waveguiding provided in the film plane. This may be achieved by making the refractive index of the film non-homogeneous, as in Fig.
BoxKarlsruhe, Germany. The ability of squeezing and guiding light in nanoscale plasmonic waveguides makes them especially interesting for photonic circuits. In spite of reported realizations of plasmonic waveguides, experimental studies on the content of plasmonic modes and mode-selective excitation methods are rare.
A strip-loaded slot waveguide is a waveguide platform allowing a large amount of degrees of freedom in terms of fabrication. Contrary to other waveguide types where the guiding layer has to be patterned, only the shape of the top layer, usually a polymer, dictates the response of this platform. We use the Finite Difference Time Domain method to study the field distribution and the modal behavior of light inside such a waveguide when the loading strip is patterned.
The mode guiding mechanism, i. SWGS mode, is a combination of surface-enhanced supermode and Bloch mode. We also design and fabricate a low-loss strip-to-SWGS mode converter.
The problem of dominant mode scattering by a symmetrically placed impedance strip in a parallel plane waveguide is solved exactly. The mode matching technique used is considerably more straightforward than the Weiner-Hopf method and is applicable to a number of other problems. Scattering by a semi-infinite impedance strip in a waveguide.
An optical waveguide is a physical structure that guides electromagnetic waves in the optical spectrum. Common types of optical waveguides include optical fiber and rectangular waveguides. Optical waveguides are used as components in integrated optical circuits or as the transmission medium in local and long haul optical communication systems.
I was trying to refer you a recent case where we tried to use equivalent refractive index for slot waveguideand I realized that you are the owner of that topic! My understanding is that while in some cases we can do some sort of averaging to simplify the problem, but generally it gets complicated when we have a gap in the structure. In one of our webinars, this problem is mentioned watch this videominutes—

Optical devices are necessary to meet the anticipated future requirements for ultrafast and ultrahigh bandwidth communication and computing. All optical information processing can overcome optoelectronic conversions that limit both the speed and bandwidth and are also power consuming. A comparative analysis of waveguides realized in different material platforms along with the propagation loss is also presented. Emerging Waveguide Technology.
