A low-complexity and efficient mmWave-over-fiber remote antenna unit (RAU) is proposed for broadband transmission and wide-angle squint-free beam steering in the full [26.5–29.5] GHz n257 5G band…
We present a low-power all-digital radio-over-fiber (RoF) transmitter for the 28 GHz band using sigma-delta modulation. Using a parallel electro-absorption modulator (EAM) structure, the radio sign…
A novel method is presented to embed finite-impulse-response filters in slow-wave Mach-Zehnder modulators. This allows to adjust the electro-optic frequency response to the designer's needs. The fi…
Exploring mmWave frequencies and adopting small-cell architectures are two key enablers for increased wireless data rates. To make these evolutions economically viable, centralized architectures ba…
We report on hybrid BiCMOS-Silicon photonics receivers with waveguide coupled Ge/Si avalanche photodiodes, designed in a lateral separate charge absorption multiplication configuration. We demonstr…
Today, the datacenter ecosystems are fueling the demand for novel transmitter (TX) technologies complying with the off-board, on-board, and chip-to-chip computing needs. This has set a new class of…
