EAM-based InP MZ modulator for 40-Gb/s PSBT using 20-Gb/s tributaries

We demonstrate a compact InP phase-shaped binary transmission (PSBT) modulator at 40 Gb/s. It consists of two electro-absorption modulators in a Mach-Zehnder configuration, each driven with 20-Gb/s tributaries with a half bit offset.
