“…The 3D image construction, reconstruction and display is also presented in this work, which can be performed by using the same system which is considered as the microring conjugate mirror(MCM). Phatharacom et al [Phatharacorn, et al, 2016], report that the MCM can be formed when the reflected power from the through and drop ports are suitably selected. The image construction can be seen at the WGM output, while the image reconstruction is obtained at the add port.…”

“…The change in the relationship between the electron mobility and the input power due to the stimuli environment of the sensor system is the sensor sensitivity. The 3D image of the activity between the sensor and the stimuli is formed by the add port output, which is the FWM output of the MCM, in which the 3D image can be formed by the 3D imaging recovery system [Phattharacorn et al, 2016;Phathracorn et al, 2018;Chaiwong et al, 2017].…”

This is the accepted version of the paper.This version of the publication may differ from the final published version.Permanent repository link: http://openaccess.city.ac.uk/19152/ Link to published version: http://dx. Abstract:The design of the microsensor system for biosensors using the plasmonic island is proposed. The sensor head is formed by the stacked layers of silicon-graphene-gold materials. The dual-mode operations of the sensor can be performed using the relationship of the changes between the electron mobility and optical phase, where the exciting environment can be light intensity(phase), electrical transient, heat, pressure, flavour and smoke, The change in light phase(intensity) in silicon and conductivity(mobility) in gold layers cause change in the output measurands. The design and simulation interpretation of the sensor is presented. The sensor manipulation using the MCM arrangement is simulated and interpreted for biosensor applications 3D imaging can also be applied to the MCM function, where the 3D in situ sensor function is possible. The sensor sensitivity of 2.0 x 10 −21 2 −1 −1 ( ) −1 via simulation is obtained.

Plasmonic op-amp circuit model using the inline successive microring pumping technique

et al. 2018

View full text Add to dashboard Cite

The electro-optic power pumping system model using the inline successive technique within the modified add-drop filter is proposed. A pumping system consists of a closed loop panda ring resonator, from which the optical power is coupled inline into the system. By controlling the two side phase modulators, the whispering gallery mode (WGM) is generated by the amplitude-squeezed light within the modified add-drop filter. By using the proposed circuits, the low current can be applied into the system via a gold layer connection, from which the amplified output current can be obtained at the throughput port, which can be functioned as the electronic operational amplifier (Op-amp). In application, the WGM output is the amplified signal that can be used for the up (down) link in free space communication network called light fidelity (LiFi). The electro-optic signals conversion can be performed by the stacked layers of silicon-graphene-gold materials. The results obtained have shown that large gain is obtained at the WGM output, which is 5 x () , when the pumping saturation time is 2 fs. It concludes the suitability of our proposed model for light fidelity, LiFi up-down link conversion.

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

et al. 2018

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.
