Planar and channel optical waveguide loss measurement using optical phase conjugation in BaTiO3

摘要

A new methodology of the propagation loss coefficient measurement with an accuracy of at least 10(-3) c,cm(-1) is demonstrated using a single-pass transmission measurement method and beam coupling based on a self-pumped phase conjugation process in a single BaTiO3 crystal. A new, high-precision optical "bridge system" for routine measurement of the planar waveguide propagation loss coefficient is designed. [References: 4]
