Abstract:
1. A method of characterizing a non-linear optical material comprising a waveguide layer, wherein the waveguide layer comprises a plurality of periodically poled domains and at least one waveguide region, the method comprising: coupling at least one diagnostic laser beam into the at least one waveguide region at one or more input locations positioned on the waveguide layer of the non-linear optical material; out-coupling the diagnostic laser beam from the waveguide region at a first output location positioned on the waveguide layer of the non-linear optical material by applying an electric field to the periodically poled domains at the first output location; measuring a first intensity level of the out-coupled beam at the first output location; out-coupling the diagnostic laser beam from the waveguide region at a second output location positioned on the waveguide layer of the non-linear optical material by applying an electric field to the periodically poled domains at the second output location; measuring a second intensity level of the out-coupled beam at the second output location; and determining a propagation loss value by determining the difference between the first and second measured intensity levels.
