Dynamic modulated Gaussian pulse propagation within the double PANDA ring resonator system

Abstract

We propose the interesting results of light pulse propagation within a double PANDA ring resonator system. We use the technique of finite difference time domain that is implemented by the scientific programming method known as OPTI-WAVE PROGRAMMING to simulate and analyze the dynamic wave forms of propagating light pulse within the desired system. By using the input Gaussian pulse with center wavelength at 1550 nm and the other practical parameters into the system, results obtained have shown that the multiwavelength light sources can be generated and achieved, and the dynamic behaviors of light pulses propagating within the system can be seen.

Analytical and simulation results of micro-ring resonator system using two eyes imaging model

“…In simulation, the WGM output can be obtained by using equation (12). After the Gaussian pulse is input into the system via input port as shown in Figure 1 [56], the resonant WGM output is obtained when the differentiation of WGM field at the ring center is vanished, the input is given by…”

“…The use of THz technology can be adopted to employ with human tissue penetration and investigation, where there are many research reported for imaging and investigations [10,11]. The interesting result of whispering gallery mode (WGM) of light within a tiny optical device to generate the 3D image basic device known as a conjugate mirror can be easily constructed by using the WGMs of light within a PANDA ring circuit [12,13]. The WGMs with THz frequency range can be generated and used to form the 3D image and linked to the optic nerves in human brain [14].…”

Storing and Harvesting Atoms/Molecules On-Chip: Challenges and Applications

“…The proposed device is made up of silica and InGaAsP/ InP with linear optical add-drop filter incorporating two nonlinear micro/nano rings on both sides of the center ring (add-drop filter). This particular configuration is known as a "PANDA" ring resonator [7] as shown in figure1. Light pulse, for instance, Gaussian, bright and dark solutions are fed into the system through different ports such as add port and through port.…”

“…The stopping light in term of signal condition can be easily performed using the whispering gallery mode concept, where the fast and slow light can be used as the upper and lower time frames or upper Figure 1: A conventional PANDA ring planar wave guide was named and designed by Uomwech et al [7] and Gold coated PANDA ring resonator for TM polarized coupling device. side and lower side peak signals for the storing light at the center as shown in figure 3, where in this case the movement (modulated signals) longer than 150 fs, i.e.…”
