Carrier-depletion Si Mach-Zehnder modulators incorporating lateral PN-junction phase shifters are reviewed in the lights of fundamental characteristics and applications to high-speed optical fiber transmission. Experimental reverse-bias supported by numerical analysis with good agreement, implying that fabricated precisely as designed. Numerical response proves shifter operates beyond 100-Gbaud symbol rate. Traveling-wave electrodes characterized S-parameter measurements reveal LRC resonance a limiting factor modulation. High-speed optical-fiber transmission on-off phase-shift keying formats is demonstrated using assembled ceramic-based metal packages.
