Flat-top CWDM Using Narrow Straight Directional Couplers on LN Thin Film

Not Accessible

Your library or personal account may give you access


A flat-top 4-channel wavelength-division multiplexer on Lithium Niobate thin film is designed and manufactured. By utilizing cascaded MZI filters and narrow straight directional couplers, the -3 dB bandwidths are ~12 nm for all channels.
