Photonic crystals are considered as the suitable structures for creating all-optical processors
because of low loss and high capability in guiding and controlling the light. This paper …

In this article, two structures are proposed for all-optical AND, XOR, and OR logic gates
based on nonlinear photonic crystals. The proposed structures include a Y-junction and ring …

A waveguide crossing mechanism based on metamaterial is proposed and numerically
investigated using finite difference in time domain method. The waveguide cross is filled with …

In this paper, wide-bandwidth low cross-talk W1 photonic crystal waveguide intersections
are proposed based on self-collimation effect. The waveguides are realized using a 2D …

The absolute instruments like the Maxwell's fisheye (MFE) lens with aberration-free imaging
properties have found interesting applications such as waveguide crossing. The flat …

Multimode waveguide crossings are crucial components for novel mode-division-
multiplexing systems. One of the challenges of multimode waveguide routing in MDM …

In this paper, two low cross-talk and wide bandwidth waveguide intersections are proposed
based on novel types of resonators which are created using rotated photonic crystal lattices …

We propose an evanescent-field interferometer in the Mach-Zehnder configuration, which
can provide an interferometric measure of the phase of evanescent fields and can be used …

We present robust control of superposition of spatial modes in a photonic crystal cavity
arising from incorporating a weak localized perturbation. As expected, this perturbation …

We present the design of a low crosstalk, high throughput waveguide intersection for
transverse-magnetic-polarized light. The design is based on two orthogonal photonic crystal …
