Photonic Terahertz Carrier Generation Using an Optical Feedback Mode-Lock Laser Diode

Photonic Terahertz Carrier Generation Using an Optical Feedback Mode-Lock Laser Diode

A tunable narrow-linewidth photonic terahertz (THz) carrier generation scheme using a distributed-Bragg-reflector-based mode-locked laser diode (MLLD) with optical feedback and mode filtering technique is proposed and experimentally demonstrated. Photonic terahertz carrier covering the D-band (110&a...
