200-Gb/s per lane intensity-modulation (IM) direct-detection (DD) optics are being
commercialized to support 800G and 1.6 T applications inside datacenters. Though IM-DD …

Electro-optic modulators are an indispensable part of photonic communication systems,
largely dictating the achievable transmission rate. Recent advances in materials and …

With the rapid development of optical communication systems, more advanced techniques
conventionally used in long-haul transmissions have gradually entered systems covering …

We demonstrate the optical transmission of an 800 Gbit/s (4× 200 Gbit/s) pulse amplitude
modulation-4 (PAM-4) signal and a 480 Gbit/s (4× 120 Gbit/s) on–off-keying (OOK) signal by …

The demand for high-speed and highly efficient optical communication techniques has been
rapidly growing due to the ever-increasing volume of data traffic. As well as the digital …

As datacenters continue to scale in size, energy efficiency for short reach (<; 2 km) links is a
major factor for networks that may connect hundreds of thousands of servers. We …

A very-high-bandwidth integrated silicon microring modulator (MRM) designed on a
commercial silicon photonics (SiP) platform for C-band operation is presented. The MRM …

The performance of high-speed intensity modulation direct detection (IM-DD) transmissions
is severely degraded by the linear inter-symbol interference (ISI), due to both bandwidth …

Employing our 47 GHz bandwidth silicon photonic (SiP) traveling wave Mach-Zehnder
modulator (TW-MZM), we demonstrate the transmission of 134 Gbaud PAM-4 (net 250 …

To meet the upcoming 6G communications challenges, terahertz-wave (THz-wave) wireless
data transmission over 100 Gb/s is urgently needed in the short term. However, advanced …
