2 April 2020Optimization of deep rib high speed phase modulators on 300mm industrial Si-photonics platform
This paper highlights the optimization of Deep Rib High Speed Phase Modulators for 400G applications thanks to the optimal choice of structure and implants through a Design Of Experiment analysis, including the proposal of a new Deep Rib HSPM with Z-implants. Results show 1,6dB gain in OMA (Optical Modulation of Amplitude) at the same cutoff frequency (fc=[2Pi*RC]-1) compared to the previous generation [1] with optimized vertical implants, and up to 2,15dB gain vs [1] with the new Z-implant Deep Rib device.
