(a) Comparison between simulated and measured 3-tap responses generated in core 4 using wavelength diversity. (b) Measured responses for all the 3-tap filters characterized by different FSRs, using wavelength diversity. (c) Comparison between simulated and measured 3-tap responses for wavelength λ3 using spatial diversity. (d) Measured responses for all the 3-tap filters characterized by different FSRs, using spatial diversity.
