All-optical ultra-compact photonic crystal NOR gate based on nonlinear ring resonators

Employing Optical Nonlinearity in Photonic Crystals: A Step Towards All-Optical Logic Gates

“…Recently more research attention has been directed towards photonic crystal logic gates (Andalib & Granpayeh, 2009, Bai eta al., 2009). In (Zhu et al, 2006) a structures for Alloptical AND gate is proposed.…”

Realization of all optical half-adder based on self-collimated beams by two-dimensional photonic crystals

“…Recently, great efforts have been made on the logic gate design through different ways such as self-collimation effect [16,17], multi-interference [18,19] and nonlinear photonic crystal ring resonator [20,21]. Different types of logic gates can be accomplished in one configuration [18] and one logic gate can operate on different wavelengths [22].…”

High contrast all-optical logic gates based on 2D nonlinear photonic crystal

“…Also nonlinear photonic crystal devices based on Kerr effect have been proposed and studied so far. All optical photonic crystal logic gates based on nonlinear ring resonator, nonlinear photonic crystal slab and multi-mode interference waveguide have been investigated [6][7][8].…”
