In the past decade, China has made great investments in studying photonics and
photocommunication with larger communication capacity, better performance, and lower …

In this paper, we demonstrate up to 260-GBaud single-wavelength coherent transmission by
employing an optical transmitter based on two wide-bandwidth devices: a novel 260-GS/s …

We demonstrated all-silicon IQ modulators (IQMs) operating at 120-GBaud 16-QAM with
suitable bandwidth, and output power. We required optical signal-to-noise-ratio (rOSNR) …

We experimentally demonstrated record rOSNR performance for both 400 Gb/s and 800
Gb/s transmissions over EDFA-only 1500 and 1000 km SSMF, respectively, by using≥ 64 …

An optical format interconversion scheme between on-off keying (OOK) and quadrature
phase shift keying (QPSK) is proposed and verified in this paper. The conversion system …

Driven by the growing data demand and the stringent power constraints on short-reach
datacenter interconnects (DCI), this work compares the driver-less (RF driver-free) …

We present our recent work on a next-generation of high-bandwidth InP MZ/IQ optical
modulator PIC with an nipn heterostructure which is ready for practical use in 130-GBd-class …

An all-silicon polarization-multiplexed modulator is demonstrated for the first time at
120GBaud-16QAM over 100-km SSMF, achieving per-polarization output power of-18.7 …

We first report the thin-film lithium niobate (TFLN) electro-optic Mach-Zehnder modulator
(MZM) on an 8-inch silicon substrate fabricated in the back-end-of-line (BEOL) of CMOS …

The interferometric fiber optic gyroscope (FOG) has been a successful commercial product
for approximately three decades, and it has been instrumental in the most demanding …
