7 September 2000 Analysis of the multielectrode linearized EA modulator
Author Affiliations +
A new approach for linearizing electroabsorption modulators (EAM) is presented here. It will be very useful for broadband, analog, radio frequency fiber-optic links. In this approach, two or more EAM will be fabricated in series on the same waveguide. Theoretical analysis shows that cancellation of both the second order and third order harmonic distortions can be obtained simultaneously by using proper electrode length and by biasing appropriately the electrodes, leading to an enhancement of the multi-octave spurious free dynamic range (SFDR). Simulation shows that the SFDR of the optical link for the two-electrode case is 10 dB larger than that for a single electrode case. Experimental confirmation of the theoretical prediction on distortion reduction is also presented.
