Abstract

. Moreover, the modulation of the observed split in the Bragg wavelength spectrum provides further insights into photothermal localization in addition to yielding photothermal information. This approach of realizing photon-molecule interaction makes fiber Bragg grating-based quantum phenomena sensing accessible and can be extended for spectroscopy, biosensing, and quantum applications.
