Optical element, optical integrated device, optical information transmission system, and manufacturing methods thereof

摘要

An optical element is formed from a molded body which is formed using an impact consolidation phenomenon in which a mechanical impact is applied to ultra fine fragile particles which are supplied onto a substrate so that the ultra fine fragile particles are pulverized and bonded to each other In the optical element, d⁶/lambda⁴<4x10^-5 nm² holds, in which d (nm) represents the average radius of a part of the molded body, such as a pore (void) or a different phase, having a refractive index different from that of a primary component of the molded body, and in which lambda (nm) represents the wavelength of light transmitting through the molded body.
