Abstract
A sensor may include one or more photonic lanterns, each including a waveguide structure with a single input waveguide at an input end and two or more output waveguides at an output end, where the two or more output waveguides of each of the one or more photonic lanterns are optically decoupled. A distribution of intensities of light exiting two or more output waveguides of each of the one or more photonic lanterns may correspond to a modal decomposition of input light coupled into the input waveguide of the corresponding one of the one or more photonic lanterns. The sensor may further include one or more spectrometers coupled to the two or more output waveguides of the one or more photonic lanterns to provide a wavelength-resolved modal decomposition of the input light.
