On-Chip Harmonically Mode-Locked Lasers in Generic Foundry as Frequency Multiplier for Optoelectronic Terahertz Generation

We experimentally demonstrated optoelectronic integrated circuits which generate selectable high-order harmonics from optical frequency combs to enable terahertz generation. These two-tone sources based on mode-locked lasers monolithically integrated with frequency multipliers are developed in an InP generic foundry approach.
