Spatial modes refer to specific patterns or configurations of electromagnetic fields in optical systems or other wave-based systems. These modes can be characterized by their spatial distribution, intensity, polarization, and phase. Spatial modes play a crucial role in various scientific fields, including photonics, telecommunications, quantum optics, and astronomy. They are used to encode and transmit information, manipulate light for imaging or sensing purposes, and create innovative optical devices. Research in spatial modes focuses on their generation, control, and manipulation to optimize performance and create new functionalities in optical systems. This includes developing methods for generating specific spatial modes, characterizing their properties, and exploring applications in fields such as optical communications, quantum information processing, and beam shaping. Overall, research in spatial modes aims to advance our understanding of light-matter interactions and improve the design and performance of optical systems for a wide range of applications.
