Abstract
It is an object to provide an optical frequency control device or the like which can quickly carry out control over a wide frequency range. The object is achieved by an optical frequency control device or the like comprised of an optical SSB modulator (), a bias voltage source () for applying a bias voltage to the optical SSB modulator (), and a modulating signal source () for applying a modulating signal to the optical SSB modulator (), wherein the modulating signal source () is provided with an arbitrary waveform generator () for generating an electrical signal with an arbitrary waveform, and an electrical signal multiplier () for multiplying a frequency of the electrical signal generated by the arbitrary waveform generator ().
