Drive-noise tolerant optical switching inspired by composite pulses [PDF]
Optics Express 28, 8646 (2020), 2020 Electro-optic modulators within Mach--Zehnder interferometers are a common construction for optical switches in integrated photonics. A challenge faced when operating at high switching speeds is that noise from the electronic drive signals will effect switching performance. Inspired by the Mach--Zehnder lattice switching devices of Van Campenhout et al.

Ultra-Efficient DC-gated all-optical graphene switch [PDF]
http://iopscience.iop.org/article/10.1088/2040-8986/ac8a5c, 2022 The ultrafast response and broadband absorption of all-optical graphene switches are highly desirable features for on-chip photonic switching. However, because graphene is an atomically thin material, its absorption of guided optical modes is relatively low, resulting in high saturation thresholds and switching energies for these devices.

Chirality in Nonlinear Optics and Optical Switching [PDF]
Molecular Crystals and Liquid Crystals, 1993 Chirality in molecular opto-electronics is limited sofar to the use of optically active liquid crystals and a number of optical phenomena are related to the helical macroscopic structure obtained by using one enantiomer, only. In this paper, the use of chirality in nonlinear optics and optical switching is demonstrated.
