Single atom movement with dynamic holographic optical tweezers

We report an experimental implementation of dynamical holographic tweezers for single trapped atoms. The tweezers are realized with dynamical phase holograms displayed on the liquid crystal spatial light modulator. We experimentally demonstrate the possibility to trap and move single rubidium atoms with such dynamic potentials, and study its limitations. Our results suggest that high probability transfer of single atoms in the tweezers may be performed in large steps, much larger then the trap waist. We discuss intensity-flicker in holographic traps and techniques for its suppression. Loss and heating rates in dynamic tweezers are measured and no excess loss or heating is observed in comparison with static traps.

A New Design Optical Tweezers by Triple Ring Resonator

We propose a new system of the multi-quantum tweezers array generation using a soliton generation control within the triple ring resonator system, whereas the dynamic tweezers can be generated within a microring device. By using the quantum processor, the entangle photon states of the tweezers can be formed, which is allowed to form the molecular quantum transmission. We have also theoretically shown that the optical tweezers can be controlled and tuned by varying the couple coefficient (κ) between 0.25 and 0.9, with ring resonator radii between 7 and 15 μm, which is available for molecule trapping. In application, the transmission of tweezers with different molecules or DNA can be performed, which is available for high density and security molecular transportation via the optical communication system.

Fast, Slow, Stopping and Storing Light Simultaneously using a PANDA Ring On-Chip

Past and slow light behaviors are the interesting aspects of light which can be useful for many fundamental and applied researches. Pornsuwancharoen and Yupapin et al. [1] have proposed the use of a simple device called “microring resonator” to perform such behaviors. In this research work, the four different behaviors of light i.e., fast, slow, stopping and storing of light where investigated using a ring resonator. 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). Nanyang Technological University scientists have also done experiment to slowing the light in microresonators using a microring system recently [6]. This concept is a concrete backbone for many applications.

Multitweezers generation using dark soliton pulses and applications

Multi-dark soliton pulses have been successfully generated by using forward and backward pumping of the S-band erbium doped fiber in the fiber optic loop, where the Stimulated Brillouin Scattering (SBS) is a nonlinear interaction between pump fields with Stokes field through acoustic wave. Results obtained have shown that the dark soliton trains can be generated and configured as the multi-optical tweezers. The advantage is that the generated tweezers are in the form of dynamic tweezers, where they can transmit/transport via the soliton communication link. The single dark soliton is also experimentally generated by using the different fiber optic scheme. We have also theoretically shown that the dynamic tweezers can be controlled and tuned, which is available for trapping and transportation in the communication link via a wavelength router. The quantum states of the transported atoms/molecules by the dynamic tweezers can be performed by using the quantum processing unit incorporating in the system.

Multiquantum tweezers generation using polarization mode identification

We propose a new system of the multioptical tweezers array generation using dark-bright soliton control within the multimicroring resonators and an add/drop filter.The dynamic tweezers are generated within an add/drop filter. By using the polarization mode identification, the entangle photon states of the tweezers can be formed, which is allowed to form the molecular quantum transmission. The number of tweezers within the add/drop filter can be tuned, amplified and quantum states of the molecule identified. The number of tweezers of 50–100 in an array with the smallest tweezer width of 2 nm is generated and achieved. We have also theoretically shown that the quantum multioptical tweezers can be controlled and tuned by varies the couple coefficient (κ) between 0.1 and 0.9, with ring resonator radii between 10 and 20 μm, which is available for molecule trapping and transportation in the communication uplink system via the add/drop filter. In application, the transmission of tweezers with different molecules or DNA or atom can be performed, which is available for high density molecular transportation via wireless communication system. © 2010 Wiley Periodicals, Inc.

Multi-variable quantum tweezers generation using photon entanglement

We propose a new system of the multi-quantum tweezers array generation using dark-bright soliton generation control within the multi-microring resonator system, whereas the dynamic tweezers can be generated within an add/drop filter. By using the quantum processor, the entangle photon states of the tweezers can be formed, which is allowed to form the molecular quantum transmission. We have also theoretically shown that the multi-quantum tweezers can be controlled and tuned by varying the couple coefficient ( κ ) between 0.1 and 0.9, with ring resonator radii between 10 and 20 μm, which is available for molecule trapping and transportation in the communication up-link system via the add/drop filter. In application, the transmission of tweezers with different molecules or DNA or atom can be performed, which is available for high density and security molecular transportation via the communication system.
