The arrival of the big data era has driven the rapid development of high-speed optical
signaling and processing, ranging from long-haul optical communication links to short-reach …

Electrical interconnects are becoming a bottleneck in the way towards meeting future
performance requirements of integrated circuits. Moore's law, which observes the doubling …

We present a subwavelength grating slot (SWGS) waveguide on silicon platform. The SWGS
waveguide is characterized by the merging of a slot structure and a subwavelength grating …

We design a novel long-range hybrid wedge plasmonic (LRHWP) waveguide composed of
two identical dielectric nanowires symmetrically placed on two opposed wedges of a …

Squeezing light to nanoscale is the most vital capacity of nanophotonic circuits processing
on-chip optical signals that allows to significantly enhance light–matter interaction by …

We design a waveguide for maximizing propagation length using the COMSOL environment
based on the finite element method. The proposed design aims to achieve a high …

An optical waveguide for working in mid-infrared range is highly desirable. However, such a
waveguide is required to yield a long propagation distance and deep subwavelength …

By exploiting the electro-absorption effect of graphene, we present a graphene-based long-
range hybrid plasmonic slot (LRHPS) waveguide modulator. The waveguide structure …

Plasmonic slot waveguides have attracted much attention due to the possibility of high light
confinement, although they suffer from relatively high propagation loss originating from the …

We present a novel design of wedge hybrid plasmonic terahertz (THz) waveguide consisting
of a silicon (Si) nanowire cylinder above a triangular gold wedge with surrounded high …
