Effect of electrode loss on the dynamic range of linearized directional coupler modulators

Numerical simulations were used to study the effect of electrode loss on the two-tone spur-free dynamic range (SFDR) of analog photonic links with linearized directional coupler modulators. Radio-frequency loss in the traveling wave electrode significantly limits the frequency bandwidth over which t...

Description
Summary:Numerical simulations were used to study the effect of electrode loss on the two-tone spur-free dynamic range (SFDR) of analog photonic links with linearized directional coupler modulators. Radio-frequency loss in the traveling wave electrode significantly limits the frequency bandwidth over which this class of electrooptic modulator can effectively enhance the SFDR
