Abstract

We present the structural analysis of prechirping bulk electroabsorption modulators (EAM's) considering the effective chirp parameter ((alpha) _eff). For an accurate estimation of (alpha) _eff, we propose a novel method that uses the modulator output intensity as a weighting factor. The transmission characteristics using (alpha) _eff obtained by the simple method have an excellent agreement with those obtained by a simulation using the dynamic small- signal chirp parameters. With this method, we perform the structural analysis of the prechirping InGaAsP bulk EAM's varying the device structures and operating conditions in terms of power penalty. From the simulation results, the relations between (alpha) _eff and power penalty is found out for the InGaAsP bulk EAM's.
