Abstract
An optical device is provided. The optical device includes a substrate and a plurality of optical structures. The substrate includes a plurality of photoelectric conversion elements. The optical structures are disposed above the substrate. Each optical structure corresponds to one photoelectric conversion element. Each optical structure includes a first portion and a second portion. The first portion has a first glass transition temperature. The second portion has a second glass transition temperature. The second portion guides the incident light into the photoelectric conversion element. The first glass transition temperature is higher than the second glass transition temperature.
