Net 3.2 Tbps 225 Gbaud PAM4 O-Band IM/DD 2 km Transmission Using FR8 and DR8 with a CMOS 3 nm SerDes and TFLN Modulators Open
We report the first 3.2 and 4.2 Tbps (8 x 225Gbaud PAM4-8), IM/DD transmission system using FR8 and DR8 configurations with TFLN modulators driven by a 3nm SerDes under the HD-FEC threshold.

Design, analysis, and characterization of a compact silicon photonic modulator with meandered phase shifters Open
We present a C-band Mach-Zehnder modulator with meandered phase shifters and a compact footprint of 432 × 260 on the silicon-on-insulator platform. Electrode, p-n junction, and optical transit time are considered when performing the…

Optimized Periodic ΣΔ Bitstreams for DC Signal Generation Used in Dynamic Calibration Applications Open
Settling time is an important performance metric in digital-to-analog converters (DACs) that are used for dynamic calibration applications. To obtain an area efficient DAC design, periodic sequences are generated from sigma-delta modulator…

Partial Pre-Emphasis for Pluggable 400 G Short-Reach Coherent Systems Open
Pre-emphasis filters are used to pre-compensate for the transmitter frequency response of coherent systems to mitigate receiver noise enhancement. This is particularly essential for low-cost, low-power coherent transceivers due to having a…

Adaptive Coherent Receiver Settings for Optimum Channel Spacing in Gridless Optical Networks Open
In this paper, we propose a novel circuit and system to optimize the spacing between optical channels in gridless (also called flexible-grid or elastic) networking. The method will exploit the beginning-of-life link margin by enabling the …

Frequency response of dual-drive silicon photonic modulators with coupling between electrodes Open
We characterize the electro-optic frequency response of a four-port traveling-wave dual-drive modulator with relatively strong coupling amongst the electrodes. We show that the electro-optic frequency response of the MZM can still be predi…

Optical and electrical trade-offs of rib-to-contact distance in depletion-type ring modulators Open
We present a study on electrical and optical trade-offs of the doping map in a ring modulator. Here, we investigate the effects of the high-doped region distance to edge of the waveguide sidewall. Four groups of ring modulators with differ…
