TL;DR: In this paper, a self-pulsating 60 GHz range quantum-dash Fabry-Perot mode-locked laser diodes (MLLD) for passive, i.e., photonic mm-wave generation with comparably low-phase noise level of -76 dBc/Hz @ 100-kHz offset from a 58.8-GHz carrier is presented.

TL;DR: In this article, a 2 A/W responsivity waveguide-uni-travelling carrier photodiode with a -3 dB electrical frequency response > 108 GHz is demonstrated.

TL;DR: In this paper, the first hybrid-integrated optical phase-lock loop (OPLL) for high spectral purity photonic terahertz sources was presented, which achieved the necessary short loop delay to lock a 1-MHz linewidth slave laser by hybrid integration of the slave laser and photodetector.

TL;DR: An heterodyne optical phase-lock loop (OPLL), monolithically integrated on InP with external phase detector and loop filter, which phase locks the integrated laser to an external source, for offset frequencies tuneable between 0.6 GHz and 6.1 GHz is presented.

TL;DR: In this article, the first monolithic integrated photonic heterodyne system that allows the two optical sources to be mutually phase locked by locking to an external optical reference was presented, where high-spectral-purity signals of up to 50 GHz were demonstrated from this first fabricated device.
