Controlling the Flow of Light Using the Inhomogeneous Effective Gauge Field that Emerges from Dynamic Modulation
Inhomogeneous Effective Gauge Field Dynamic Modulation
2013/8/7
We show that the effective gauge field for photons provides a versatile platform for controlling the flow of light. As an example we consider a photonic resonator lattice where the couplin...
Controlling the Flow of Microscopic Particles—The Role of Beam Size
Optical Manipulation Optical Tweezers Directional Flow
2012/12/28
Flow of micro particles and fluids is important in many microscopic systems. Here we present details of our finding of a directional flow of micro particles due to a single beam optical trap. It was f...
Realizing effective magnetic field for photons by controlling the phase of dynamic modulation
effective magnetic photons controlling dynamic modulation
2012/8/7
The goal to achieve arbitrary control of photon flow has motivated much of the recent research on photonic crystals and metamaterials. As a new mechanism for controlling photon flow, we in...
Experimental demonstration of two methods for controlling the group delay in a system with photonic-crystal resonators coupled to a waveguide
two methods controlling group delay system photonic-crystal resonators coupled waveguide
2011/8/10
We measure the group delay in an on-chip photonic-crystal device with two resonators side coupled to a waveguide.We demonstrate that such a group delay can be controlled by tuning either the propagati...
A Novel Dispersion Controlling Technique Using Doped Ring Structures within Photonic Crystal Fibers
Dispersion Photonic Crystal Fibers Ring Structures
2011/5/14
We proposed the novel photonic crystal fiber structure which uses high/low doping material around each cladding holes. Through the numerical analysis, we confirmed that this fiber structure will intro...
Principle of the Phase Controlling of the SBS Wave and its Application to the Beam Combination Laser for the Laser Fusion Driver
Stimulated Brillouin scattering Phase control Phase conjugate mirror
2009/6/1
The phase control of the stimulate Brillouin scattering (SBS) wave by a standing wave is the most important technique for the realization of the beam combination laser system. In this work, a theoreti...
