Plasmonic Op-Amp Circuit Model using the Inline Successive Microring Pumping Technique
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 ~5×10-6cm².(V.sW)-1, when the pumping saturation time is ~2 fs. It concludes the suitability of our proposed model for light fidelity, LiFi up-down link conversion

In-situ 3D Micro-sensor Model using Embedded Plasmonic Island for Biosensors
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 × 10−21 cm2 V−1 s−1 (mW)−1 via simulation is obtained
A single eye 3D image perception device using vertical double ring resonator construction
A single eye three-dimensional (3D) imaging perception using a single 3D imaging pixel is designed and manipulated, which is the interesting device configuration that can be used for various applications. The device configuration is consisted of double conjugate mirrors that can be vertically fabricated, which can be used to form the 3D image using a single pixel configuration, from which the large area device construction is also possible. By adjusting the microconjugate mirror parameters, then the matching between both microconjugate mirrors can lead to obtain the required 3D images. Results obtained have shown that the 3D image outputs can be achieved and used for 3D pixel imaging. The 3D image output can be confirmed by the four-wave mixing output balancing profile, which is achieved. In applications, the large area 3D images can be constructed using the large area 3D imaging device, from which the large area can be coverage by the microconjugate mirror array, which can be useful for various applications
