In the paper, we review our work on heterogeneous III-V-on-silicon photonic components
and circuits for applications in optical communication and sensing. We elaborate on the …

Optical Frequency Comb (OFC) generated by semiconductor lasers are currently widely
used in the extremely timely field of high capacity optical interconnects and high precision …

With the mass development of mobile data transfers, wireless communications have recently
entered a new area: the carrier frequency is now entering the THz region. After a brief …

We present an optoelectronic mixer for the terahertz (THz) frequency-domain based on an
iron-doped InGaAs layer integrated in a plasmonic microcavity. We show that this structure …

We demonstrate a tunable continuous-wave (CW) terahertz (THz) homodyne system with a
novel detuned dual-mode laser diode (DML) and low-temperature-grown (LTG) InGaAs …

Studies about random lasing phenomena taking place in disordered structures with
amplification are gaining great interest, as they can support dual wavelength lasing without …

Thanks to a portable dual-frequency Brillouin fiber laser and a 1.55? μm photomixer, we
report the generation of a highly coherent kilohertz level submillimeter wave emission. Low …

We studied theoretically coherent phenomena in the multimode dynamics of single section
semiconductor ring lasers with quantum dots (QDs) active region. In the unidirectional ring …

The mode coherence of adjacent and non-adjacent spectral modes of a passively mode
locked quantum dash (QDash) semiconductor laser are deduced through radio frequency …

We demonstrate an integrated distributed feedback (DFB) laser array as a dual-wavelength
source for narrowband terahertz (THz) generation. The laser array is composed of four …
