Tailoring Ince-Gaussian arrays based on a computer-generated hologram.

The continually expanding interest in Ince-Gaussian modes has arisen due to their highly complex and widely varying spatial structures, which allow these fascinating diverse light modes to be significant to various topics. In this paper, we propose a technique for generating beam arrays that contain four Ince-Gaussian modes. By utilizing a single digital hologram, the intensity distributions of each mode in the array can be manipulated independently and flexibly. This work provides a feasible method to realize the controllable multiplexing of Ince-Gaussian modes, which has potential application in numerous important areas.
