Abstract:
1. A driver for a number N of electro-optical interface cores each driven by a respective output stage of a multi-stage electro-optical modulator, the driver configured to receive an electrical modulating signal at an input and comprising: an input impedance matching stage; a pre-conditioning circuit configured to generate a number M, of delayed replicas of the electrical modulating signal, wherein M is an integer divisor of the number N of cores; an array of M launch buffers of the replica signals; and an array of M multi-delay blocks, each multi-delay block comprising a plurality of delay circuits differently cascaded on distinct signal paths, said array of M multi-delay blocks configured to receive, at respective inputs, the M replica signals, and to output N/M differently delayed replicas of the M replica signals, and each driving a corresponding output stage of one on said N electro-optical interface cores.
