Title:
OPTICAL SENSOR AND METHOD FOR FORMING SAME
Document Type and Number:
WIPO Patent Application WO/2018/061898
Kind Code:
A1
Abstract:
In order to provide an optical sensor that is capable of obtaining both an optical trap effect and a moth eye effect with a single texture structure, a semiconductor optical sensor according to the present invention includes a light absorption medium that has a refractive index n and a thickness sufficiently less than a light transmission length, wherein the center wavelength to be observed is defined as λ. The semiconductor optical sensor is characterized by: having, in a light incident surface, a texture structure having a random surface direction and a typical structure scale d defined as in (λ/n)
