Configurable Modulator for Pure Phase Modulation [PDF]
2019 Photonics North (PN), 2019 We present a configurable silicon modulator for pure phase modulation, implemented as a Mach-Zehnder interferometer with a PN carrier depletion modulator (CDM) and tunable couplers. The spurious intensity modulation introduced by the CDM is compensated by tuning the splitting ratios of the couplers and the phase delay between the arms.
