We report 50Gb/s On-Off keying (OOK) and 40Gb/s binary phase shift keying (BPSK) modulation in a single-drive push-pull silicon Mach-Zehnder modulator with optimized segmented electrode design. The measured modulation efficiency (Vπ·Lπ) is ȼ1.77 V·cm at 4.0 V reverse bias and the electro-optic (EO) 3-dB bandwidth exceeds 30 GHz at 6.0 V reverse bias.
We report our initial experimental demonstration of electrically tunable Fano resonance line shapes by using racetrack ring microresonator-coupled Mach-Zehnder interferometers with embedded p-i-n diodes on silicon-on-insulator substrates. Fano resonance observed at the interferometer output ports is due to interference between the guided lightwave that is coupled to the microresonator and the coherent...
