High-Speed Modeling of Ultracompact Electrooptic Modulators

Bandwidth of Linearized Electrooptic Modulators

Many schemes have been proposed to make high dynamic range analog radio frequency (RF) photonic links by linearizing the transfer function of the link’s modulator. This paper studies the degrading effects of finite transit time and optical and electrical velocity dispersion on such linearization schemes. It further demonstrates that much of the lost dynamic range in some modulators may be regai...

Ultra High Speed LiNbO3 and Polymer Electrooptic Modulators in Lightwave Optical Access Communication Networks

In the present paper, we have been modeled parametrically and numerically the high speed of materials based electrooptic (EO) modulators in advanced optical communication systems. The modulated bandwidth is deeply and parametrically studied over wide ranges of the affecting sets of parameters via specially designed software which processes the interaction of causes and effects. The design param...

Distortion in Linearized Electrooptic Modulators

AbstructIntermodulation and harmonic distortion are calculated for a simple fiber-optic link with a representative set of link parameters and a variety of electrooptic modulators: simple Mach-Zehnder, linearized dual and triple Mach-Zehnder, simple directional coupler (two operating points), and linearized directional coupler with one and two dc electrodes. The resulting dynamic ranges, gains, ...

High Operation Efficiency of Semiconductor Electrooptic Modulators in Advanced Lightwave Communication Systems

Device modeling, Integrated optics, Optical modulator, EO modulator, and Silicon optoelectronics Photonic links have been proposed to transport radio frequency (RF) signals over optical fiber communication systems. External optical modulation is commonly used in high performance RF photonic links. The practical use of optical fiber communication systems to transport RF signals is still limited ...
