Abstract: A method of manufacturing an optical coupler that includes: preparing a light-transmitting substrate having a first main surface and a second main surface aligned in a first direction; applying a first photosensitive glass paste containing a first filler to the first main surface; arranging a grayscale mask formed in a binary pattern on the second main surface; emitting an ultraviolet ray to the second main surface to expose the first photosensitive glass paste; removing the grayscale mask from the second main surface and developing the first photosensitive glass paste; and removing the light-transmitting substrate from the first photosensitive glass paste developed and curing the first photosensitive glass paste, wherein a longest length of the first filler is larger than a wavelength of the ultraviolet ray.
