Apparatus for detecting cross-talk and method therefor |
摘要 |
An apparatus for detecting cross-talk and method therefore, wherein a first and a second output signal from a wavelength selective device are directed to be coincident upon a photodetector. A homodyne beat signal results from the coincidence of the first and the second output signal and the homodyne beat signal is used to measure wavelength drift.
