Ultra-fast electro-optic switching control using a soliton pulse within a modified add-drop multiplexer

Abstract

We have proposed the use of a soliton pulse that propagates within a modified add-drop filter, which is made of a GaAsInP/P material. It is in the form of a Panda-ring resonator, from which a bright/dark soliton pulse is input into a system via an input port. The conversion between bright and dark soliton pulses is introduced at the 3dB coupler, i.e. the change in phase of π⁄2. But it is not superimposed each other. The output solitons obtained at the through and drop ports are bight and dark solitons respectively. Both signals can be used to form "ON' and "OFF" or "1" and "0", which are useful for the digital bit generation. The switching speed of the system can be improved by employing the two nonlinear side rings. In application, secure output bits can be arranged by using the alternative input solitons or the control ports, where the input bright and dark solitons can be converted into output bits. This means that the output bits can be randomly switched between "1" and "0", which can be identified by the sender. Moreover, the additional information can be multiplexed via the add port and transmitted in either free space or optical fiber via the whispering gallery mode and through port outputs. Finally, the electro-optic switching can be transferred and the electronic switching by the embedded stacked layers, where the ultrafast switching of light input can lead the ultrafast electrical switching speed. The switching speed of ~5 fs and the offset time of ~220 fs of the "on" and OFF" are achieved by using the selected ring parameters.

“…In this case, both electrical and optical sensors can be applied in terms of the change in the electron mobility and wavelength, respectively. Moreover, the remote charger using the amplified WGM beam power and the mobility output is also available from LiFi distributed nodes.…”

Microring stereo sensor model using Kerr–Vernier effect for bio-cell sensor and communication

“…By using the Kerr-Vernier effect within the two identical microring systems, the changes in the refractive index of the microring material due to the difference Kerr effect is induced by the input power variation. By using the electro-optic material such as silver ChG, the center ring ChG can be changed to be the silver chalcogenide glass, in which the coupling between the electron mobility and transient electrical quantity can give the change of the change in phase of light [34,35]. The electro-optic crosstalk of the sensor signal is converted from the optical crosstalk that can be the more appropriate application of cell communication investigation.…”

“…Therefore, a variation of the optical intensity will lead to changes in the OPD of the light in the system. Changing the light's phase within the system can be due to the electron mobility caused by mixing the ChG ring with the metallic material, for an instant, silver, thus, the electron mobility (µ) in the ChG-silver can be changed [34,35], from which the excited electrons are affected to the system output, which is related to the group velocity (V d ) of the waves, therefore the device acts as sensor. The light intensity can be described by I= 2 = ( ) 2 as the V d =µE and E is the applied electric field to the transducer as the sensing system in which an electric current can be established with a density of J s as J s =σE.…”
