Optical temperature sensor with micro ring resonator and graphene to reach high sensitivity
摘要： In this paper, micro temperature sensor with micro ring resonator and graphene material has been investigated. The main idea is to control the temperature of system by the layer of graphene on micro ring resonator path. By rising the temperature of the system, graphene with 5000 W/mK thermal conductivity senses this increase and applies it in sensor resonance peaks. The linear temperature difference causes a linear difference in sensitivity, power, and energy level, which shows the correct functioning of the system. Electronic sensors suffer from electrical disturbances and electromagnetic interference and sometimes do not function properly, therefore this micrometer optical sensor with 44×40 μm dimensions is necessary in industrial and medical fields because it has small dimension, high finesse and sensitivity, low weight and cost in comparison with other sensors. Other materials of this sensor are Si and SiO2 which are natural elements and have a high melting point. The FSR and FWHM of system are 660 GHZ and 30 GHZ which are acceptable values in comparison with other optical sensors. The time rotation and time delay unit reaching to 0.31 ps and 1.51 ps in accordance which have an acceptable time and also total length of ring is 94 μm.

摘要： This paper details the novel design, simulation and analysis of the digital photonic single-bit magnitude comparator with the utilization of silicon micro-ring resonator as its core component. The micro-ring resonator uses electro-optic carrier injection modulation properties with its ring waveguide being structured in PIN diode. Five micro-ring resonators are used in the proposed design, with each corresponds to the specific logic mode operation. This work also presents the time varying simulation, where two predetermined 1-bit input stream is injected into the circuit at the data rate of 1 Gbps, where its output is observed via oscilloscope, where results are obtained at the sampling rate of 1.6 THz. The timing diagram for the entire simulation is also shown together with additional results obtained from the simulation.

Digital electro-optic full adder design and simulation
摘要： This paper demonstrates the circuit design of an electro-optic full adder based on silicon micro-ring resonator as its core component. The ring resonator design incorporates the carrier-injection forward-biased PIN waveguide structure for its logical operation. This work also provides the working principle of the designed full adder. It also proceeds with the demonstration and analysis of the operation with two digital input bits information together with a Carry-In (CIN) bit input injected at 1 Gbps, and the output generated as SUM output as well as Carry-Out (COUT) both at the same data rate generated. The performance of the proposed circuit design is verified by clear output timing waveforms, following the sequence of the digital full adder logic table.

[Institution of Engineering and Technology 7th Brunei International Conference on Engineering and Technology 2018 (BICET 2018) - Bandar Seri Begawan, Brunei (12-14 Nov. 2018)] 7th Brunei International Conference on Engineering and Technology 2018 (BICET 2018) - Thermal-based wavelength reconfigurable digital electro-optic D-type flip-flop
摘要： This paper demonstrates the design of a thermally reconfigurable/tunable operating wavelength of the digital electro-optic D-type flip-flop. The design of the D flip-flop is based on the silicon micro-ring resonator as its core component. The optical modulation technique incurred in the micro-ring resonator utilizes the carrier-injection forward-biased PIN ring waveguide. Micro-heaters are applied to the proposed design with controlled heat generation in order to modulate the operational wavelength, thus allowing the proposed design to operate at varying wavelength. This work proceeds with the simulation and time-varying analysis of the proposed design at the data rate of 1Gbps, and the clocking speed of 5Gbps. Two different operating wavelengths of 1550nm and 1552nm are used to show that the proposed design is wavelength reconfigurable via thermal tuning.

Digital Electro-Optic Exclusive OR and NOR Gates Utilizing a Single Micro-Ring Resonator
摘要： In this paper, we present the concept design and implementation of a single silicon-based micro-ring resonator in order for it to operate as exclusive OR and NOR mode. The micro-ring resonator utilizes carrier-injection based electro-optic modulation scheme, with modulation voltage ranging from 0V up to 1.4V. A single micro-ring resonator is used to simultaneously generate both XOR and XNOR digital output mode operation at the drop as well as through port respectively. The modulation voltage required for the proposed design together with its operation wavelength is found by resonance spectra analysis on the ring. Time domain simulations where two electrical information bit streams of 10 Gbps data rate injected into the circuit design have been carried out to display its working operation.

摘要： With the development and application of Internet of things, new requirements for optical communication technology are put forward, and this text proposed a new optical information processing device design logic-oriented-based for Internet of brain things application. Three micro rings were coupled with three different shapes of optical waveguide components, their wavelengths were varied with the change of the applied voltages (logical input) so as to control the propagation direction of the input optical signal and the final output forms of lighting or darkness representing different logic level values as the result of the logical operations. The working wavelength of the device was determined as 1.5146μm through static simulations with Matlab tools, and it was proved that the functions of flexible optical switch logic operations "and/not", "or/nor" and "xor/xnor" can be realized in the dynamic simulations, the results indicated that the device with low-power consumption, high-bandwidth, flexible structure and multiple logical operation functions has been accomplished and can be used as components of VLSI designs in future. This work also give a useful reference to many Internet of brain things applied field.
