Abstract
Nonlinear optical polymers are gaining increasing research interests for high frequency photonic device applications, in particular, broadband modulators in commercial communication systems. the unique features of these materials allows the fabrication of integrated optical modulator chips that are compact, lightweight, and broadband at a low cost. With the advances in material synthesis and device fabrication, the application of polymer electro-optic modulators in commercial fiber-optic data links becomes increasingly realistic. We report our design, fabrication and packaging of polymeric integrated electro-optic Mach- Zehnder intensity modulators, as well as their test results including halfwave voltage, frequency response, optical insertion loss, on-off ratios, etc. We have inserted our packaged modulators into commercial fiber optical data links for applications tests. The standard tests procedures for the cable television industry are used and the results are compared to current commercial NTSC multi-channel cable television transmitter units with directly modulated lasers or LiNbO3 external modulators. The stability issues including thermal stability, photochemical stability and bias control stability have been investigated and will be discussed. The bottle-neck technical issues that may affect device design, fabrication, and applications will also be discussed.
