Performance Projection of Electro-Optical Modulators for Radio-Over-Fiber in 2 GHz Cryogenic Front-End Receivers
2005
IEEE transactions on applied superconductivity
We present the design of a Y-Ba-Cu-O on LiNbO 3 cryogenic electro-optical modulator for analog 2 GHz applications. A resonant configuration of coplanar electrodes is considered, showing improvements with respect to both resonant Au electrodes and to traveling-wave electrodes, even beyond the traveling-wave theoretical maximum performance limit. The optimized layout is presented featuring a reduced length of 8.26 mm. Index Terms-Coplanar waveguide, high temperature superconductor, LiNbO 3 , Mach-Zehnder electro-optical modulator, resonance.
