Tailoring Large Asymmetric Laguerre–Gaussian Beam Array Using Computer-Generated Holography

Laguerre–Gaussian beams are structured light with a donut-shaped symmetric intensity profile and helical phase profile. The beam is defined by quantized parameter known as the mode number which extends to infinity. availability of unbounded modes makes these promising candidate for next-generation optical computing, communication technologies. can be made asymmetric through certain techniques term ‘asymmetric beams’. Here, asymmetricity adds another degree freedom (apart from its number) helps in encoding more information compared beam. However, order harness benefits all available degrees freedom, it required generate large such multiplexed fashion. we report generation array first time. Computer-generated holography spatial multiplexing were employed comprising 12 × 16 = 192 an arbitrary index asymmetricity.
