ABSTRACT
A novel design of molecular buffer for molecule storage and delivery using a PANDA ring resonator is proposed. The optical vortices can be generated and controlled to form the trapping tools in the same way as the optical tweezers. In theory, the trapping force is formed by the combination between the gradient field and scattering photons, which is reviewed. By using the intense optical vortices generated within the PANDA ring resonator, the required molecules can be trapped and moved (transported) dynamically within the wavelength router or network, ie, a molecular buffer. This can be performed within the wavelength router before reaching the required destination. The advantage of the proposed system is that a transmitter and receiver can be formed within the same system, which is available for molecule storage and transportation.

f4-ijn-6-575: Result of the dynamic tweezers within the buffer with different (a) wavelengths and (b) coupling constants, where Radd = 10 μm, RR = RL = 100 nm.

Mentions: In simulation, the bright soliton with center wavelength at 1.50 μm, peak power 2W, pulse 35fs is input into the system via the input port, and the coupling coefficients are given as κ0 = 0.5, κ1 = 0.35, κ2 = 0.1, and κ3 = 0.35, respectively. The ring radii are Radd = 10 and 30 μm, RR = 50 and 100 nm, and RL = 50 and 100 nm, respectively. To date, the evidence of a practical device with a radius of 30 nm has been reported by Piyatamrong et al.19 Aeff are 0.50, 0.25, and 0.25 μm2. In this case, the dynamic tweezers (gradient fields) can be in the form of bright solitons, Gaussian pulses, and dark solitons, which can be used to trap the required microscopic volume. There are four different center wavelengths of tweezers generated; the dynamical movements are seen in Figure 4, where (a) /E1/2, (b) /E2/2, (c) /E3/2, (d) /E4/2, (e) through port, and (f) drop port signals, where in this case all microscopic volumes are received by the drop port. In practice, the fabrication parameters which can be easily controlled are the ring resonator radii instead of the coupling constants.
