Arbitrary scanning of the Airy beams using additional phase grating with cubic phase mask

Abstract

To controllably deflect the Airy beam in a wide range dynamic, the method of combining the classical Airy cubic phase with a diffraction blazed grating phase was adopted in this paper. By dynamically adjusting the grating parameters, the transverse self-accelerating Airy beam allows arbitrary deflection, and the deflected position can be controlled precisely. The mathematical model of the Airy beam optical field distributions generated by the combined phase patterns were proposed to explain the feasibility. Its correctness was ultimately demonstrated by the experimental results. It is significant to use this method for the Airy beam deflection control in high-precision closed-loop aiming systems.

Generation and propagation of Airy beams and 1-inch diameter focusing optics using three-dimensional-printed polymer optics

“…The phase mask is generated numerically by discretizing the cubic phase over a 0.78 cm×0.78 cm area of the SLM with a pixel size of 7.8 μm. A blazed grating phase modulation is superimposed along the x direction of the cubic phase mask to deflect the modulated light into its first diffraction order, separating it from unmodulated light that remains in the zeroth order 19 …”

“…The conventional method to generate these beams includes a spatial light modulator (SLM) to impart the desired phase mask on an incident beam. 3 However, this method usually required a Fourier Transform (FT) lens which makes the optical system bulky and thus, difficult to incorporate in photonic integrated circuits (PICs). 4 Moreover, the larger pixel size of SLM affects the performance of optical systems.…”

Anomalous Propagation Characteristics of Airy Beam in Nonlinear Kerr Media

“…This study on the new Airy beams and other non-diffractive beams has become a hot area in recent years. Recently, most attention has been concentrated on the generation of Airy beams [4][5][6][7][8], particular Airy beams [9][10][11][12][13], the control of particular beams [14][15][16] and the potential application of these beams, such as the directional control of particles [17] and the generation of light bullets [18,19].…”
