Abstract
An optical receiver () includes an electrical signal generation unit (), a first phase compensation unit (), a distortion compensation unit (), and a first dispersion compensation unit (). The electrical signal generation unit () generates an electrical signal on the basis of received signal light. The first phase compensation unit () performs a phase rotation compensation process on the electrical signal generated by the electrical signal generation unit (). The distortion compensation unit () performs a dispersion compensation process and a phase rotation compensation process in this order, at least once, on the electrical signal after having compensation performed thereon by the first phase compensation unit. The electrical signal generation unit (), the first phase compensation unit (), and the distortion compensation unit () are incorporated into one semiconductor device.
