Abstract
In an example method of forming a waveguide part having a predetermined shape, a photocurable material is dispensed into a space between a first mold portion and a second mold portion opposite the first mold portion. A relative separation between a surface of the first mold portion with respect to a surface of the second mold portion opposing the surface of the first mold portion is adjusted to fill the space between the first and second mold portions. The photocurable material in the space is irradiated with radiation suitable for photocuring the photocurable material to form a cured waveguide film so that different portions of the cured waveguide film have different rigidity. The cured waveguide film is separated from the first and second mold portions. The waveguide part is singulated from the cured waveguide film. The waveguide part corresponds to portions of the cured waveguide film having a higher rigidity than other portions of the cured waveguide film.
