“Optomechanically induced nonreciprocal intermodal phase modulation by sub-GHz acoustic phonons” dataset

The prefix is the name of each mode, and files without the F symbol are the phonon vibration mode diagrams of each optical mode measured by an oscilloscope. Files with the F symbol are the phonon spectra obtained by Fourier transform; In the FIG2 folder, the Gain factors folder contains the forward stimulated Brillouin gain measurements for three optical modes, including raw data files, data plotting files, standardized processing files, and code.

The Opto coeff folder contains the acousto-optic coupling coefficient diagrams for the three optical modes, with prefixes representing different modes. The TE01 mode mode field simulation diagram, unnormalized acousto-optic coupling coefficient diagram, and raw data are included in folder 1. Subfolders 4 and 5 contain the same content for the TM01 mode and HE11 mode; The FIG3 folder contains the acoustic mode Fourier transform measurement maps of TE01 mode in PCF with different air ratios.
