Silicon intensity Mach–Zehnder modulator for single lane 100 Gb/s applications
TL;DR: In this paper, a substrate removal technique in a silicon Mach-Zehnder modulator (MZM) is proposed and demonstrated to improve modulation bandwidth based on the novel and optimized traveling wave electrodes, the electrode transmission loss is reduced, and the electro-optical group index and 50 Ω impedance matching are improved simultaneously.
Journal ArticleDOI
Low-loss and fabrication tolerant silicon mode-order converters based on novel compact tapers.
TL;DR: The simulation results show that high conversion efficiencies can be readily achieved over a wavelength range from 1520 nm to 1580 nm for all of the proposed devices and have negligible degradations under normal width and thickness deviations.
Journal ArticleDOI
Design and demonstration of ultra-high-Q silicon microring resonator based on a multi-mode ridge waveguide
TL;DR: The design and experimental demonstration of the ultra-high-Q-factor silicon microring resonator based on a multi-mode ridge waveguide is presented, designed to decrease the propagation loss and to improve the Q factor.
Journal ArticleDOI
Highly efficient silicon optical polarization rotators based on mode order conversions.
TL;DR: The novel silicon optical polarization rotators (PRs) based on the TM(0)-TE(n)- TE(0) mode conversions inside the waveguide show the insert losses of less than 0.4, 0.5, and 1 dB, respectively.
