Abstract: The present invention provides a method for fabricating small right angle prism mirrors, projecting system, and small right angle prism mirrors fabricated by a semiconductor process. The method comprises: coating a reflecting layer on a top surface of a glass substrate; forming an optical glue layer on a bottom surface of the glass substrate; utilizing a mold to form a 3D shape on the optical glue layer; exposing the optical glue layer having the 3D shape to solidify the optical glue layer having the 3D shape and combine the glass substrate having the reflecting layer and the optical glue layer having the 3D shape; removing the mold to form a small prism array; and dicing the small prism array to generate a plurality of small right angle prism mirrors.

Abstract: An optical element including a substrate, a first optical film and a second optical film. The first optical film and the second optical film are disposed on at least one side of the substrate and are both formed on the substrate. The first optical film has a first surface facing away from the substrate and a plurality of first optical microstructures disposed on the first surface. The second optical film has a second surface facing away from the substrate and a plurality of second optical microstructures disposed on the second surface. The orthogonal projection of the first optical microstructures on the substrate does not overlap the orthogonal projection of the second optical microstructures on the substrate. A wafer level optical module adopting the optical element is also provided.

Abstract: The optical component includes a first substrate, a first diffractive layer formed on the first substrate, a second substrate, a second diffractive layer formed on the second substrate, and a bonding material disposed between the first substrate and the second substrate and connecting the first substrate and the second substrate. The second diffractive layer is disposed opposite to the first diffractive layer, and both the first diffractive layer and the second diffractive layer are located between the first substrate and the second substrate. A gap is formed between the first diffractive layer and the second diffractive layer.

Abstract: A diffractive optical element and method for fabricating the diffractive optical element are provided. The diffractive optical element includes a substrate, a first diffractive structure layer and a second diffractive structure layer. The substrate has a first surface and a second surface opposite to the first surface. The first diffractive structure layer is disposed on the first surface of the substrate. The second diffractive structure layer is disposed on the second surface of the substrate. In the method for fabricating the diffractive optical element, at first, the substrate is provided. Then, a first glue material layer/first semiconductor layer is formed and patterned on the first surface of the substrate. Thereafter, a second glue material layer/second semiconductor layer is formed and patterned on the second surface of the substrate.
