components, based on optical frequency domain reflectometry technique. Successful experimental work validates the compact system on silicon nitride, including dispersion-free spatial domain response of an arrayed waveguide grating.
We report our progress on an integrated interferometric testing engine for integrated components, based on optical frequency domain reflectometry technique. Successful experimental work validates the compact system on silicon nitride, including dispersion-free spatial domain response of an arrayed waveguide grating.
