Patent abstract
A cubic element of photonic crystal is integrally formed on the surface of a photo-detection element, and a portion of the photonic crystal cubic element is irradiated with ultraviolet rays thereby to change the refractive index of the portion of the cubic element that has been irradiated with ultraviolet rays. Alternatively, by causing globular particles having different refractive indices to eject on the surface of the photo-detection element from an ink-jet apparatus having a nozzle provided with a temperature control part by controlling temperature of the nozzle to form a laminate of globular particle layers having different refractive indices, a photonic crystal lens is integrally formed on the surface of the photo-detection element.
