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

Client-side optics are facing an ever-increasing upgrading pace, driven by upcoming 5G
related services and datacenter applications. The demand for a single lane data rate is soon …

This article presents an optical transmitter front-end based on 2: 1 analog multiplexer
(AMUX) for beyond-1-Tb/s/carrier coherent optical communications systems. An AMUX is …

We demonstrate the transmission over 10.2-km SMF of intensity-modulated and direct-
detected (IM-DD) signals at record 700.4 Gb/s line rate and record 538.8 Gb/s net rate with …

Simple high-speed optical transmission technologies are desired for use in intra-and inter-
datacenter networks. In this study, we demonstrate simple single-carrier intensity-modulated …

We demonstrated a 1.3-Tbps/carrier signal transmission over 200 km in 175-GHz-spaced
4.2-THz WDM configuration. A 168-GBaud PDM probabilistically-shaped-64QAM signal with …

It is very attractive to apply a directly modulated laser (DML)-based intensity-modulation and
direct-detection (IM/DD) system in future data centers and 5G fronthaul networks due to the …

To cope with the rapid growth of communications traffic, 400-Gb/s/ch digital coherent
systems are being deployed in optical core networks. However, further scaling is required …
