Proposed Nonlinear Microring Resonator Arrangement for Stopping and Storing Light

New Communication Bands Generated by Using a Soliton Pulse within a Resonator System

“…The storage light pulse within a storage ring (R s or R 4 ) is achieved, which has also been reported by Ref. [7]. In applications, the increasing in communication channel and network capacity can be formed by using the different soliton bands (center wavelength) as shown in Figure 2, where 2(h) 0.51 m, 2(i) 0.98 m, 2(j) 1.48 m and 2(k) 2.46 m are the generated center wavelengths of the soliton bands.…”

“…A soliton pulse, which is introduced into the multi-stage micro ring resonators as shown in Figure 1, the input optical field (E in ) of the soliton input is given by an Equation (1) [7]. where A and z are the optical field amplitude and propagation distance, respectively.…”

“…However, several problems are required to solve and address, for instance, the problem of solitonsoliton interaction and collision [5], and the waveguide structure that the broadband soliton can be confined [6]. In this letter, we propose the technique that can be used to generate the new soliton communication bands (wavelength bands), whereas the common soliton pulse, i.e., a soliton source is at the center wavelength of 1.55 m. The soliton bands at the required center wavelengths can be stored [7] and filtered by using the add/drop filter [5]. In application, the use of super dense wavelength multiplexing, with the long distance link is available.…”

Contemplation and perception energy transition states

“…In the meditation, the spirit signal is confined by a single frequency (energy), where the oscillation time will be reduced and ended up by the smallest value(or zero), which means that the spirit is a single peak signal at the stopping in time situation [15]. While, in this situation the energy level is transformed from two-level atom to be eight and 16 levels with different energy values, which are shown in Figures 1 and 2, respectively.…”

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

“…Nowadays, stopping or cooling light beam has become the promising technique for atom/molecule trapping investigations (using static or dynamic tweezers), especially, after the announcement of Nobel Prize 2012 in Physics on the whispering gallery modes [2,3]. There are two more kinds of devices that can be used to trap light beams, the use of microcavity arrays performed by Yanik and Fan [4], and nonlinear microring resonator by Yupapin and Pornsuwancharoen [5] for stopping light (laser beam). Ang and Ngo have also done experiment to slow the light in microresonators using a microring system recently [6].…”
