title = "Bandwidth optimization of germanium-doped silicon optical modulator for high-speed applications",
abstract = "This paper analyzes a germanium-doped silicon traveling wave Mach-Zehnder modulator (TWMZM) for high speed operation at 1550 nm wavelength. Single arm drive modulator performance using non-return-to-zero on-off keying (NRZ-OOK) driving scheme has been investigated. The phase-loss characteristics of the graded-index silicon-germanium PN phase shifter have been determined numerically. The traveling wave electrode has been designed for 1.5 mm long phase shifter. The 3 dB modulation bandwidth of the designed TWMZM is calculated to be 31 GHz at-2 V and an error-free operation of 59 Gbps has been obtained for 2 V peak-to-peak drive voltage with an extinction of ∼6 dB.",
