Beat-spectrum design for 100-km-range optical correlation-domain reflectometry with localized 15-cm resolution
Takaki Kiyozumi, Yuta Higa, Soshi Yoshida +4
Conventional optical correlation-domain reflectometry (OCDR) based on sinusoidal frequency modulation exhibits a coupling between measurement range and spatial resolution because b…
High-Spatial-Resolution Optical Correlation-Domain Reflectometry with 100-km Measurement Range
Takaki Kiyozumi, Soshi Yoshida, Yuta Higa +4
In the maintenance of optical fiber networks, there is a growing demand for high-precision measurement of optical loss distribution and fault locations over long distances. In this…
Repetition-Rate-Difference Tunable Dual-Comb Fiber Laser Using Bidirectional Lyot filtering
Yuanjun Zhu, Bowen Liu, Maolin Dai +4
Single cavity dual-comb fiber lasers adopting different multiplexing configurations are benefited from the natures of common-mode noise suppression and superior coherence. Particul…
GHz fundamental mode-locking of a highly integrated Er-doped all-fiber ring laser
Maolin Dai, Bowen Liu, Yifan Ma +4
High repetition rate ultrafast fiber lasers are important tools for both fundamental science and industry applications. However, achieving over GHz repetition rate in passively mod…
