Abstract:
A test structure that supports the characterization of an optical component comprising:an input port for receiving an input signal; first and second test ports for optically connecting said test structure to said optical component, said first test port being optically connectable to said input port such that said input signal can be supplied to said optical component through said first test port; a first optical path for receiving a first optical response signal from said first test port, said first optical response signal resulting from application of said input signal to said optical component; a second optical path for receiving a second optical response signal from said second test port, said second optical response signal also resulting from application of said input signal to said optical component; and means for combining a first portion of said input signal with said first optical response signal and for combining a second portion of said input signal with said second optical response signal.
