Thickness-dependent slow light gap solitons in three-dimensional coupled photonic crystal waveguides

Abstract

The thickness-dependent multimodal nature of three-dimensional (3D) coupled photonic crystal waveguides is investigated with the aim of realizing a medium for controlled optical gap soliton formation in the slow light regime. In the linear case, spectral properties of the modes (dispersion diagrams), location of the gap regions versus the thickness of the 3D photonic crystal, and the near-field distributions at frequencies in the slow light region are analyzed using a full-wave electromagnetic solver. In the nonlinear regime (Kerr-type nonlinearity), we infer an existence of crystal-thickness-dependent temporal solitons with stable pulse envelope and use the solitonic pulses for driving quantum transitions in localized quantum systems within the photonic crystal waveguide. The results may be useful for applications in optical communications, multiplexing systems, nonlinear physics, and ultrafast spectroscopy.

An Optical Logic Gate Based On 2-Dimensional Photonic Crystals with High Operating Contrast Ratio And Fast Response Time

“…Nowadays, the most common application of optical technology in ber-optic telecommunication networks is for high-speed connections such as server racks, terminal connections, WANs [1] Photonic crystals are effective structures for making new arti cial materials with controlled light characteristics for special functions [2]. It is necessary to mention that, before the development of photonic crystals, the control of light in dielectric environments was impossible, and the only way to use the properties of light was in a re ected state against different materials [3,4]. Studies of photonic crystal based logic gates are divided into broad categories of photonic crystal interference based logic gates, photonic crystal resonator based logic gates and photonic crystal self-collimating logic gates Salmanpour et al (2014) [5].…”
