“…Distributed transmission line sessions are included at the signal generator and load ends to take the slow-wave mode propagation characteristic of the modulating signal on the electrodes into account. The EAM part can often be modeled using a series resistance and capacitance , and a dynamic photocurrent-resistance [7]. The dynamic photocurrent resistance must be included to predict the effect of the optical power on the electrical-to-optical (E/O) response.…”

Abstract-In this paper three options for very-high bit rate integrated electro-absorption modulated laser (EML) structures are investigated using electromagnetic simulation. A physics based distributed equivalent circuit model taking the slowwave propagation characteristics of the modulation signal into account is proposed for the electro-absorption modulator (EAM) electrode arrangement. This model makes it possible to apply an EM/circuit co-simulation approach to estimate the electrical to optical transmission bandwidth for the integrated EML. It is shown that a transmission bandwidth of 70 GHz seems feasible with the investigated EML structures if the driving impedance is reduced to 25 . It is also shown that the influence of electromagnetic cross-talk between components can be neglected in the estimation of the transmission bandwidth even in the case of very short separation zones. Finally, a slight decrease in transmission bandwidth is observed for an EML structure without ground pillars.

We designed two kinds of flip-chip bonded electro-absorption modulated laser on AlN or Si carrier, working at 100 Gb s À1. A theoretical comodeling approach based on 3D electromagnetic and circuit simulations has been applied and validated by measurements. As demonstrated, integration and behavior of future complex opto-electronic modules could be optimized applying such EM-based approach. V C 2010 Wiley Periodicals, Inc.

“…Previously, EM simulations of EAMs have been performed by substitution of the MQW stack in the EAM diode junction with a dielectric material having an average permittivity [12]. In this work a different approach is followed in that a lumped small-signal equivalent circuit model for the MQW stack in A high anode contact resistance can substantially reduce the frequency response and hence the bandwidth of the device.…”
