Optical integrated circuit and optical transceiver

Abstract

An optical integrated circuit includes a first element having a function of separating each polarization from electromagnetic waves including multiple polarizations, or a function of rotating at least some of the polarizations after separating each polarization from electromagnetic waves including multiple polarizations, and a second element having a function of separating components of multiple wavelengths included in the electromagnetic waves into components of each wavelength. The first element and the second element are connected to each other in a cascade-like manner.

Dependencies are inferred from the claim text.
