Mode sorting receivers for super-resolution imaging
Abstract
In this project, we will pursue a theoretical analysis that will help generate fundamental understanding of optimal extraction of image-information embedded in the phase of incoherent light that physics allows, by measuring the information-bearing light in the optimal modal basis. Our design and development of highly-efficient spatial mode demultiplexers using nano-photonic grating couplers will take as input the complete specification of device functionality in terms of a set of input and output modes, and the desired coupling efficiencies between them. This will allow us to pack multiple functionalities into a single device (e.g., wavelength demultiplexing grating couplers), making it an ideal choice for designing a fully general spatial mode demultiplexer. The hardware we will develop may have a wide technological applicability, e.g., in quantum enhanced receivers for lasercom, free-space QKD using multiple spatial modes, as well as various adaptive transmitter and receiver methods for imaging through highly scattering media.
