Combined Franz-Keldysh and quantum-confined Stark effect waveguide modulator for analog signal transmission

Comparison and Linearization of LiNbO3 and Semiconductor Modulators

“…For example, in EO modulators, the third intermodulation distortion has been eliminated by placing the Mach Zehnders in parallel [3,4] and series [5] configurations. Electroabsorptive modulators can also be linearized with series [6,7] combinations. Alternatively, careful selection of the DC bias can reduce distortion in EA [8] and ER [9,10] modulators.…”

Large Signal Performance of the Electroabsorption Modulator

“…Thus, for the electroabsorption modulator characterized by the exponentially decaying transfer curve with second-order Downloaded by [National Sun Yat-Sen University] at 08:04 27 December 2014 exponent of equation (1), it is impossible to simultaneously nullify the second-and third-order intermodulation products. However, at least in theory, it is possible to build an electroabsorption modulator characterized by an exponentially decaying transfer function with fourth-order polynomial exponent [11]. Simultaneous minimization of secondand third-order intermodulation distortion of such a modulator is feasible [11].…”
