광 주파수 빗으로부터 단일 광 주파수 성분의 선택적 추출 = Selective Extraction of a Single Optical Frequency Component from an Optical Frequency Comb

다국어 초록 (Multilingual Abstract)

Mode-locked pulse lasers have a temporal periodicity up over a short period of time. However, in the time-frequency domain, a pulsed laser with temporal periodicity is described as an optical frequency comb with constant frequency spacing. Each frequency component of the optical frequency comb in the frequency domain is then a continuous-wave (CW) laser with hundreds of thousands of single-frequency-component CW lasers in the time domain. This optical frequency comb was developed approximately 20 years ago, enabling the development of the world’s most precise atomic clocks and precise transmission of highly stable optical frequency references. In this review, research on the selective extraction of the singlefrequency components of optical frequency combs and the control of the frequency components of optical combs is introduced. By presenting the concepts and principles of these optical frequency combs in a tutorial format, we hope to help readers understand the properties of light in the timefrequency domain and to develop various applications using optical frequency combs.
