Claim 5:
6. The method of claim 1, prior to refracting the first incident ambient light beam at the first interface, further comprising refracting an incident ambient light beam at a second interface between a respective one of a plurality of cavity chambers and a second medium on a side of the respective one of the plurality of cavity chambers away from the respective one of the plurality of lens portions to generate the first incident ambient light beam;
wherein the plurality of cavity chambers are spaced apart from each other, and respectively cover the plurality of lens portions;
the respective one of the plurality of cavity chambers spaces apart the respective one of the plurality of lens portions from the low refractive index modulation layer; and
the respective one of the plurality of cavity chambers has a third refractive index smaller than the second refractive index.
