Abstract
An optical transmitter includes a signal-process circuit to process a transmission signal; an optical modulator to modulate light input by the transmission signal output from the signal-process circuit, and output an optical signal; and a control circuit to output a control signal for controlling a carrier frequency of the optical signal, to the signal-process circuit, wherein the signal-process circuit comprises a phase-rotation circuit to apply phase rotation of the carrier frequency on a complex plane according to the control signal, to the transmission signal, a map-adjustment circuit to determine scale factor for a map according to an angle of the phase rotation, and a modulation-format-map circuit to map the transmission signal on the complex plane based on a modulation format and the scale factor, wherein the phase-rotation circuit is configured to rotate, on the complex plane, the phase of the carrier frequency mapped based on the scale factor.
