Abstract
For a 40 Gbit/s DPSK optical transmission system, two circuits are reported. The first circuit is a high frequency, high power modulator driver based on a twin traveling wave amplifier (combiner) with an active power divider circuit and measured output voltages greater than 7 Vpp. A second circuit consisting of a differential preamplifier and TWA main stages is presented with concept and simulation results.
