Recently, State Key Laboratory of Transient Optics and Photonics, Xi’an Institute of Optics and Precision Mechanics (XIOPM) completed development of experimental principle prototype of “femto fiber optical frequency comb light source”, a sub-project under the national special project of development of major scientific instrument from the Ministry of Science & Technology, and delivered the prototype to relevant user, marking the project has shifted from prototype R&D to engineering application.
The sub-project “femto fiber optical frequency comb light source” was established in Jan. 2012. Since then, the R&D team, in more than two years’ hard works, has experienced the process from scheme demonstration, validation of experimental principle to R&D of principle prototype, tackled many key technologies and finally developed the double-femto all-polarization maintaining fiber optical frequency comb system, with main technological innovation and performance characteristics of: 1. Difference between repetition frequency of femto optical frequency comb single-set system and that of double-set system adjustable; 2. Combination of coarse adjustment active tracing and fine adjustment frequency locking adopted, guaranteeing long-time and wide-range service of the system; 3. Frequency-phase linkage of double-femto all-polarization maintaining fiber optical frequency comb firstly realized; 4. All-polarization maintaining fiber solution adopted, realizing generation, amplification and compression and frequency/phase stabilization of femto fiber laser and guaranteeing system stability and reliability, with system frequency stability of 1×10-12@1s and phase stability of 5×10-10@1s. Invention patent for relevant technologies has been filed.
Successful development of the system marks a new step of XIOPM in femto optical frequency comb technology and application, and lays solid theoretical and technological foundations for development in microwave photonics of XIOPM.
