Bend Waveguides on Silicon Nanowire Optical Waveguide (SNOW)
In a previous work, we reported a novel optical waveguide named silicon nanowire optical waveguide (SNOW), which consists of arrayed silicon nanowires acting like an effective-index medium.

Lectures on Theory of Microwave and Optical Waveguides [PDF]
The lecture notes document the mathematical theory of microwave and optical waveguides. We start with reviewing preliminary background from Maxwell's equations. Then we discuss hollow waveguides, and inhomogeneously-filled waveguides, coupling of waveguides and cavities, discontinuities in waveguides.

We propose and experimentally demonstrate a novel approach to implement a low-loss, broadband, and compact transverse electric (TE)-pass polarizer on a silicon-on-insulator platform.

Analytic Expressions for Orbital Angular Momentum Modal Crosstalk in a Slightly Elliptical Fiber
Assuming weakly guiding approximation, we examine orbital angular momentum (OAM) mode mixing on account of ellipticity in a fiber and derive a complete set of analytic expressions for spatial crosstalk, using scalar perturbation theory that incorporates ...

Design of graphene-based polarization-insensitive optical modulator
By exploiting the electroabsorption effect of graphene, we present a graphene-based polarization-insensitive optical modulator. The waveguide structure consists of a silica substrate, high-index silicon strip waveguide, Si3N4 dielectric spacer, two ...

Giant Birefringence of Periodic Dielectric Waveguides
The giant (Δn >; 1.5) and broadband achromatic birefringence is realized by periodic dielectric waveguides (PDWs), which benefit from low loss transmission, compact size, and simple structure.

Quasi-flat bands in waveguide arrays [PDF]
Coupled electromagnetic waves propagating in a waveguide array are discussed. This waveguide array can be considered as one dimensional photon crystal composed from the unit cell containing three different waveguides, namely, two positive refraction index waveguides and one waveguide with negative refraction index.

Integrated liquid core AntiResonant Reflecting Optical Waveguide (ARROW) are used as basic component for the realization of complex optofluidic devices. Liquid core ARROW waveguides permit to confine the light in a low refractive index liquid core, by means of two high refractive index cladding layers designed to form a high reflectivity Fabry-Perot ...

Mobile Waveguides: Freestanding Waveguides Steered by Light [PDF]
Microstructured optical fibers (MOFs) and photonic crystal fibers (PCFs) offer advanced photonic and microfluidic functionalities in a single, integrated platform. This unique combination constitutes the main axis for the emerging “lab-in-fiber” protocol.
