研究目的
Investigating the experimental observation of polarization modulation instability (PMI) effect in all-normal dispersion microstructured optical fibers (ANDi MOFs) with picosecond pumping at 1064 nm.
研究成果
The experimental observation of PMI in ANDi MOFs with picosecond pumping at 1064 nm was successfully reported. The study provides insights into the conditions under which PMI can be observed and its implications for optical fiber technology.
研究不足
The study is limited to the observation of PMI in specific types of ANDi MOFs under picosecond pumping at 1064 nm. The effects of other wavelengths or pumping conditions were not explored.
1：Experimental Design and Method Selection:
The study involved pumping ANDi MOFs with picosecond pulses at 1064 nm to observe PMI.
2：Sample Selection and Data Sources:
Two types of microstructured optical fibers (MF1 and MF2) were used, with their chromatic dispersion and birefringence properties characterized.
3：List of Experimental Equipment and Materials:
A microchip Nd:YAG laser emitting linearly polarized pulses of 700 ps duration at 1064 nm, half-wave plate (HWP), and the MOFs.
4：Experimental Procedures and Operational Workflow:
The fibers were pumped, and the output light spectrum was analyzed for two orthogonal polarization orientations of the pump.
5：Data Analysis Methods:
Theoretical calculations of the wavelength shift of PMI bands as a function of pump wavelength were compared with experimental data.
