Nonlinear Coupling Effects of Waves in A Panda Ring

Abstract

All forms of waves in circular motions in circular ring resonator have shown the interesting behaviors, especially, in the nonlinear wave tracks, where the waves such as gravitation wave, sound wave, electromagnetic wave, matter wave and water wave can produce the whispering gallery modes (WGMs) with some certain conditions. This paper presents the use of a circular resonator (ring resonator) which is coupled by two nonlinear side rings known as a PANDA ring, in which the input waves can be in the forms of soliton, Gaussian pulses, photon or matter wave and introduced into the system. The WGMs can be generated due to the coupling effects of the two nonlinear side rings with the center ring and tunneling effects, which have shown many interesting results and aspects. Some expected outputs can be in the forms of surface plasmons, potential wells, leaky modes of waves, whispering gallery modes, matter waves (photons or particles). The use of WGMs for water wave and Rabi oscillation of photons (particles) in a PANDA ring are also discussed.

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

“…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].…”

“…THz radiation consists of electromagnetic waves with frequency between 0.1 THz to 10 THz, and is widespread biomedical application involving the interaction of terahertz pulse with biological media [31][32][33][34][35][36], where THz radiation has been used successfully as a noninvasive imaging technique for detection of human skin cancer [37,38]. Recently, Yupapin et al have shown the interesting results of whispering gallery mode of light within a PANDA ring circuit [13,14], in which the advantage is that the WGMs can be easily generated and controlled within the PANDA ring circuit, which can be useful for various applications. The other applications of Panda ring resonator can be found in references [39][40][41][42][43][44][45][46].…”

PSYCHIATRIC INVESTIGATION USING WGMs IN MICRORING CIRCUITS

“…However, searching of new techniques remain. Recently, Yupapin has reported an interesting technique of light behaviors that use whispering gallery modes (WGMs) of light in a PANDA ring, 13 which can be easily applied for nerve/cells communications, 14 i.e., remote monitoring, where the use of microscale device based on microring resonator circuits has shown promising challenges. By using this proposed technique, mobile communication link of the psychiatric investigation can be formed via the radio frequency generated by the microring circuits, which will be detailed in the following paragraph.…”

“…Here, the center ring is coated with Au or other conducting materials, e.g., Ag, Cu, etc. This particular con¯guration is known as a \PANDA" ring resonator 13,26 and is shown in Fig. 1.…”

Conjugate Mirror by a Panda Ring Circuit

“…Till now, however, we still search for the new techniques that can show the advantage over the past components. Recently, Yupapin [5] have proposed the very interesting technique that uses WGMs in a PANDA ring waveguide for many applications [6,7].…”
