Theory of acousto-optic fiber Bragg grating coated with zinc oxide (ZnO)

摘要

In summary, we have modified the theory of an optical fiber acousto-optic Bragg grating using piezoelectric ZnO coating. The theory agrees well with the experimental result previously demonstrated. It can be seen that the transmitted wavelengths in terms of a few nanometres can be fine-tuned by either adjusting the piezoelectric ZnO thickness or electrical power applied to the transducer.
