Thermal Modelling of Silicon Photonic Ring Modulator with Substrate Undercut

Silicon dual-ring modulator.

A silicon electro-optic modulator based on coupled microring resonators is proposed. The dual-ring modulator has wide optical bandwidth, high extinction ratio and low insertion loss. A simple integrated circuit connecting the two rings allows for fast modulation speed of >40 Gbit/s. This device has both improved optical and electrical performance over a single-ring modulator. The dual-ring modu...

Silicon Micro-Ring Modulator Modeling

Ring resonator-based photonic microwave receiver modulator with picowatt sensitivity

The authors report an enhanced LiNbO3 microdisk photonic microwave receiver modulator with a sensitivity of 3 pW (285 dBm) and a bandwidth of 60 MHz centred at 14.6 GHz. The sensitivity of the modulator is improved by using a critically coupled microwave ring resonator and a modified ground plane for passive E-field amplification and confinement.

Ultrafast pulse-amplitude modulation with a femtojoule silicon photonic modulator

Ultrahigh-speed optical interconnects are essential to future cloud computing. Further increase in optical transmission speed has been hindered by power consumption and limited bandwidth resources, for which integrated optical transceivers using advanced modulation formats, such as pulse-amplitude modulation (PAM), are a promising solution. We report 80 Gb∕s PAM operation of a silicon microring...
