International audienceThis letter presents experimental characterization of an integrated reflective electroabsorption modulator and semiconductor optical amplifier (REAM-SOA) device in the radio-over-fiber (RoF) context. Orthogonal frequency-division-multiplexing (OFDM) modulation condition optimizations have been carried out by varying the temperature, the voltage biasing of the modulator, and the current applied to the semiconductor amplifier
This paper describes a co-modelling approach based on electromagnetic and electro-optic simulations. Such approach is applied to the design of a Mach-Zehnder intensity modulator (MZI) at four lanes integrated on Z-cut lithium niobate, applied to a QPSK modulation. As we will see, our original procedure contributes to the optimization of QPSK modulator behaviour. The theoretical and experimental results are encouraging.Index Terms -Hybrid approach, Lithium niobate, MachZehnder interferometer, Modulator, QPSK, Quadri-Drive Modulator.
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.
