Non-volatile Optical Switch Based on a GST-Loaded Directional Coupler [PDF]
, 2018 We present a non-volatile optical switch based on a directional coupler comprising a silicon-Ge2Sb2Te5 (GST) hybrid waveguide. The non-volatility of GST makes it attractive for reducing static power consumption in optical switching.

Simulation of 1 x 2 OTDM router employing symmetric Mach-Zehnder switches [PDF]
, 2005 In high-speed all-optical time division multiplexed (OTDM) routers it is desirable to carry out data routing, switching, clock recovery and synchronisation in the optical domain in order to avoid the bottleneck due to optoelectronics conversion.

All-optical switching in epsilon-near-zero asymmetric directional coupler
Scientific Reports, 2022 We propose an all-optical switch based on an asymmetric directional coupler structure with epsilon-near-zero (ENZ) layer. The nonlinear optical properties the of ENZ layer are analyzed by hot-electron dynamics process, and the all-optical operating ...

Ultrafast and High Extinction Ratio 1×4 Electro-Optical Switch Based on Cascaded Dual-Output MZI
IEEE Photonics Journal, 2023 We propose and fabricate an ultrafast and high extinction ratio 1 × 4 optical switch based on a cascade, dual-output Mach–Zehnder interferometer (MZI) on the lithium niobate platform. The optical switch consists of cascaded, identical, dual-

Simulation of an all-optical 1 x 2 SMZ switch with a high contrast ratio [PDF]
, 2007 — An all-optical 1×2 high contrast ratio (CR) switch based on the symmetric Mach-Zehnder (SMZ) interferometers is presented. Simulation results show a remarkable improvement of the inter-output CR (~25 dB) between the two outputs compared with an ...

Hybrid InGaAsP-InP Mach-Zehnder racetrack resonator for thermooptic switching and coupling control [PDF]
, 2005 An InGaAsP-InP optical switch geometry based on electrical control of waveguide-resonator coupling is demonstrated. Thermooptic tuning of a Mach-Zehnder interferometer integrated with a racetrack resonator is shown to result in switching with ON-OFF ...
