We report on the resonance characteristics of a Si-based ring resonator model with the theory of multiple-beam interference.
When illuminated at near-normal incidence, a multiple-beam interference is generated that results in the maxima and minima in the reflectance or transmittance spectra.
Moreover, novel PBG aperiodic structures defined by recursive substitutional sequences like one-dimensional (1D) and 2D Thue-Morse patterns cannot be realized even in principle by multiple-beam interference.
To understand the mechanism of the periodic number dependence of the crystallization power threshold, we calculate the reflectivity of the three amorphous periodic film samples studied before according to the multiple-beam interference theory of multilayer film[16].
Actually, one can find that the real absorbed power threshold of each sample is almost identical regardless of laser incidence from the substrate or film side if one calculates the absorptivity of each sample based on multiple-beam interference of multiple layer films for the two incidences of each sample from the substrate and film sides.
A Master Curve, capable of describing all possible configurations, was deduced by using the so-called Wigner Distribution Function, for a cylindrically-symmetric array of interfering beams, of the type utilized nowadays for optical tweezers and multiple-beam interference optical cages.
To mitigate this interference between the scanning patterns and intrafractional movement, the tumor may be covered with multiple beam scans.
In addition to single beam scans, a multiple beam scan can also be performed.
The quality of the surface ordered structures prepared by laser beam interference depends strongly on the regularity of interference pattern.
This result can be explained by considering that, unlike the under-filling Gaussian beam method, spatial shaping of the excitation light for a holographic beam results from the interference of multiple beams with a wide range of incident angles, thus permitting to take advantage of the large numerical aperture of the objective.
