Band-Gap Solitons in Nonlinear Photonic Crystal Waveguides and Their Application for Functional All-Optical Logic Gating

Vakhtang Jandieri et al.

Summary: This review paper summarizes the propagation characteristics of band-gap temporal solitons in photonic crystal waveguides with Kerr-type nonlinearity and the realization of functional and easily scalable all-optical logic gates. By using gap-solitons as signal carriers and operating in the true time-domain, stable pulse envelopes are maintained during logical operations, enabling easy realization of multiple concatenated all-optical logic gates for ultrafast full-optical digital signal processing. The proposed logic gates' efficiency and scalability are validated using rigorous theoretical formalism and full-wave computational electromagnetics.

Soliton Rectangular Pulses and Bound States in a Dissipative System Modeled by the Variable-Coefficients Complex Cubic-Quintic Ginzburg-Landau Equation

Yuan-Yuan Yan et al.

Summary: The study focused on the complex cubic-quintic Ginzburg-Landau equation and calculated the analytic one-soliton solution of the variable-coefficients CQGLE. It was found that rectangular dissipative soliton pulses of the variable-coefficients CQGLE can be effectively realized and controlled, breaking through the energy limitation of soliton pulses and potentially providing a theoretical basis for the preparation of high-energy soliton pulses in fiber lasers.

An optimized design of all-optical XOR, OR, and NOT gates using plasmonic waveguide

Amrindra Pal et al.

Summary: All-optical logic gates have great potential in ultra-high-speed Boolean operation and logical computation. This study proposes XOR, OR, and NOT gates using metal-insulator-metal waveguides with a smaller footprint than previously reported. The device's performance is analyzed using the finite-difference time-domain method (FDTD) and verified through MATLAB simulation, with an extinction ratio of 27.80 dB. These logic gates can serve as key components in optical communication and pave the way for new designs in plasmonic integrated circuits.

Bright and dark optical solitons for (3+1)-dimensional Schrodinger equation with cubic-quintic-septic nonlinearities

Abdul-Majid Wazwaz

Summary: This study addresses soliton propagation in a sixth-order nonlinear Schrodinger equation with fourth-order and sixth-order dispersive terms influenced by cubic-quintic-septic nonlinearities. Bright and dark optical soliton solutions are formally derived, with constraints on parameters for determining these solutions. Other ansatze are employed to determine additional singular and periodic solutions. The findings could enhance understanding of wave dynamics in cubic-quintic-septic nonlinear materials such as chalcogenide glass.

A review on all-optical logic adder: Heading towards next-generation processor

Kamanashis Goswami et al.

Summary: This paper provides a review of literature on all-optical adders, focusing on designs utilizing SOA, plasmonics, and PhC platforms. SOA designs offer high contrast ratios but with higher response times and operating power, while plasmonic designs provide miniaturized physical footprints with fabrication challenges. In contrast, PhC designs exhibit superior light propagation characteristics, higher operating power, and bandwidth compared to other designs.
