Enhancement of Electromagnetic Force by Localized Fields in One-Dimensional Photonic Crystal

Abstract: Abstract-In 1-D photonic crystal with structural defects, localized mode results in strong electromagnetic fields around the position of the defect. Thus, the strong fields enhance the tangential force on a lossy dielectric layer, as well as normal force on the perfect dielectric slab. The results of this study suggest a class of micro-machines driven by electromagnetic wave, such as sunlight or microwave.

“…4 (2), into a positive loop formed by the movement measuring the interferometer signal that is the real-time velocity signal provided by a very sensitive vibration meter (7,9,11) processed through an Schmitt trigger circuit, which controls the output of the pumping laser and chopper (5,6). This means that when the bifoil device starts moving, the circuit immediately blocks the laser light by means of the chopper.…”

“…Normally, the radiation pressure is too small for these kinds of applications. 5 Nonetheless, some resonance principles can be used to significantly increase the force, for instance, by using a waveguide made of lossless dielectric blocks, where the direction of the force exerted on the dielectric is parallel to the waveguide axis. 6,7 A second approach is with a Bragg waveguide based on a Fabry-Perot cavity in which the peak of the force only appears at the structures' resonant frequencies and the force is normal to the waveguide wall.…”

“…3 The radiation pressure produced with these motors, however, is normally too small to move large objects with practical relevance. 4 Certain resonance principles can be used to significantly increase the force associated with electromagnetic wave-driven micromotors. First, a waveguide consisting of lossless dielectric blocks can be used.…”

“…Employing photonic crystal fiber in conjunction with a Bismuth based Erbium doped fiber, aims to reduce gain medium length [13]. As a result of the higher nonlinearity of photonic crystal fibers [14][15][16][17][18][19][20][21][22] and hence the lower pump power required, the generation of higher order Stokes is made easier enabling the interference between the pump wave and higher order Stokes waves to generate microwave to millimeter waves using a Brillouin laser [23]. Also the dynamics of active mode locking is analyzed to show the required time to reach steady state, the width of pulses produced, and the threshold condition for mode locking [24].…”
