摘要：A method of operating a wavelength swept source apparatus includes generating a single mode light, and generating a basic optical comb including light rays having identical frequency differences with adjacent light rays by modulating the generated single mode light. The method further includes generating other optical combs that include the same number of light rays as that of light rays of the optical comb that has a frequency band different from that of the basic optical comb, and is distributed in a frequency band wider than that in which the basic optical comb is distributed, by modulating the light rays of the basic optical comb. The light rays of the basic optical comb and the light rays included in the other optical combs are sequentially emitted according to frequencies of the light rays of the basic optical comb and the light rays included in the other optical combs.

主权项：1. A method for operating a wavelength swept source apparatus, the method comprising: generating single mode light; generating a first modulation result of the generated single mode light; generating a second modulation result of the generated single mode light, the generating of the second modulation result being performed in parallel to the generating of the first modulation result; generating a basic optical comb based on the first modulation result and the second modulation result, the basic optical comb comprising a plurality of light rays having identical frequency differences with adjacent light rays; generating a plurality of optical combs by modulating the plurality of light rays, each of the plurality of optical combs including the same number of light rays as the plurality of light rays, each of the light rays included in the plurality of optical combs having identical frequency differences with adjacent light rays, each of the plurality of optical combs having a different frequency band from that of the basic optical comb, which does not overlap therewith, and the plurality of optical combs being distributed in a wider frequency band than that in which the basic optical comb is distributed; and sequentially emitting, from the wavelength swept source apparatus, the plurality of light rays and the light rays included in the plurality of optical combs according to frequencies of the plurality of light rays and the light rays included in the plurality of optical combs, over a lapse of time.
