An empirical model for high yield manufacturing of 10Gb/s negative chirp InP Mach-Zehnder modulators

Compact Optical Comb Generator Using InP Tunable Laser and Push-Pull Modulator

“…The tunable laser emitting 13 dBm is co-packaged with a push-pull modulator (total loss including input/output coupling loss of about 6 dB) with a bandwidth of ~10 GHz. Fuller details are given in [16,17]. Besides Eq.…”

Electronic dispersion precompensation for 10.709 Gbit/s NRZ-OOK using InP and LiNbO 3 Mach-Zehnder modulators

“…Precompensating transmitter and signal generation: Compared to widely available LiNbO 3 MZMs, InP MZMs are attractive because of the smaller required drive voltage, reduced size, increased stability and monolithic integrability with other optoelectronic devices such as lasers and optical amplifiers [2]. In particular, InP MZMs are suitable for small industry-standard packages.…”

“…The required drive voltages are synthesised from a digital signal processor followed by a 6-bit, 21.418 GSa/s DAC and drive amplifier. The InP MZM is a p-phase-shift device designed to achieve near zero-chirp across the C-band [2]. The output signal from a dual-drive MZM is given by…”

“…where S i and S o are the input and output power splitting ratios, which are equal to 0.5 and 0.63, respectively, for the InP MZM, and 0.5 for the LiNbO 3 MZM [2]. V 1 and V 2 are the voltages applied to the two arms of the modulator, a(V) and Dw(V) are the voltage-dependent attenuation and phase constants, and L is the interaction length for the arms of the modulator.…”
