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 …

Over the past decade, high-speed communications technologies have reached severe
scalability limits, from short-reach electrical chip-to-chip interconnects to ultra-long-haul …

We developed an InP-based coherent driver modulator (CDM) with a flexible printed circuit
(FPC) RF interface. The CDM has a 3-dB electro-optic (EO) bandwidth of over 85 GHz …

We demonstrate a new optical-domain bandwidth extension technology with a simple
optical configuration. We use an integrated optical phase-interleaving in-phase-and …

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 …

This article highlights recent developments in high-speed photodiodes and their role in
efficient data transmission. Design considerations and state-of-the-art performances are …

We designed and fabricated a compact and low-cost ultrabroadband amplifier module. The
3-dB-down-cutoff frequency (f3dB) of the module is 108 GHz with direct-current (dc) block …

The performance of a wideband coherent receiver was investigated. The relative impact of
digital pre-distortion, geometric constellation shaping and pilot sequence detection, as well …

The use of multiple segments on a silicon photonic modulator can increase bandwidth at the
cost of greater complexity in the driving signals. We propose and demonstrate a simple …
