ABSTRACT:
A method comprises: formulating a design input and output optical signals; computing an interference pattern between the simulated input and output optical signals; computationally deriving a diffractive element arrangement from the computed interference pattern; forming a mask pattern corresponding to the derived diffractive element arrangement; and forming the diffractive element set on a substrate surface by projecting the mask pattern. An optical surface grating comprises a set of diffractive elements on a substrate. The arrangement of the diffractive elements is computationally derived from an interference pattern computed for interference at a substrate surface between a simulated design input and output optical signals. An optical spectrometer comprises: an input optical port for receiving an input optical signal into the spectrometer; an output optical port for transmitting an output optical signal out of the spectrometer; and an optical surface grating as described hereinabove.
