Reflective semiconductor optical amplifier fiber cavity lasers (RSOA-FCLs) are appealing, colorless, self-seeded, self-tuning and cost-efficient upstream transmitters. They are of interest for wavelength division multiplexed passive optical networks

An important challenge in optical communications is the generation of highest-quality waveforms with a Mach–Zehnder modulator with a limited electrical swing (Vpp). For this, we discuss, under limited Vpp, the influence of the waveform design on th

We present a comparative study of the capacity increase brought by bit- and power-loading discrete multi-tone (DMT) modulation for low-cost colorless transmitters. Three interesting reflective semiconductor optical amplifier (RSOA) based colorless tr

Space division multiplexing increases the capacity of mobile cells by reusing the frequencies in various directions. Yet, today’s concepts scale badly to millimeter wave and therefore cannot provide Tb/s capacity. In this paper, we introduce time-t

A new method for simple and robust in-building motion detection is introduced. The proposed technique relies on a single frequency continuous wave (CW) signal and can therefore be integrated with inexpensive commercial off-the-shelf (COTS) components

In this paper, we demonstrate ultra-fast millimeter wave beam steering with settling times below 50 ps. A phased array antenna with two elements is employed to realize beam steering. The phased array feeder is implemented with a recently introduced t

We introduce and demonstrate an optical beamformer concept based on a spatial light modulator that enables independent steering and shaping of a large number of beams. In addition, our microwave photonic based system has a relatively small volume and

Radically novel approaches will be needed to support the 1,000 times increase in data rates expected from next-generation wireless communications (5G). Integrated microwave photonics (IMWP) techniques have been identified as an enabling technology fo
