Abstract: An optical filter may include a first reflector and a second reflector. The first reflector may include a plurality of first gratings having a first sub-wavelength dimension and being arranged to recur at a first interval in a first direction. The second reflector may be spaced apart from the first reflector and include a plurality of second gratings having a second sub-wavelength dimension and arranged to recur at a second interval in a direction parallel to the first direction. The first reflector and the second reflector may include different materials or different geometric structures from each other. Accordingly, it is easy to adjust the transmission wavelength characteristics of the optical filter.

Abstract: A method of designing a meta optical device is provided. The method includes: setting, via a processor, design data for arrangement and dimensions of a nanostructure of the meta optical device, according to a function to be implemented by the meta optical device; obtaining a phase change graph with respect to a change in the dimensions; setting a shape dimension region with phase defect in the phase change graph; and substituting a shape dimension with phase defect, which is included in the shape dimension region with phase defect among the dimensions included in the design data, with a substitution value that is outside the shape dimension region with phase defect. Accordingly, a meta optical device having no phase defect is implemented.
