AUTOMATIC AND PROGRAMMABLE SIGNAL GENERATION METHOD IN THE RADIOFREQUENCY, MILIMETER WAVE AND TERAHERTZ FREQUENCY REGIONS WITH LOW PHASE NOISE, WIDE FREQUENCY TUNING RANGE, HIGH MODULATION BANDWIDTH AND HIGH FREQUENCY RESOLUTION

摘要

A method for automatically generating signals in the radiofrequency, milimeter wave and terahertz frequency regions with low phase noise, wide frequency tuning range, high modulation bandwidth and high frequency resolution is hereby provided. The method of the invention is related to Optical Injection Locking (OIL) techniques and allows proper injection of lasers, a slave laser and a master laser, by determining the most suitable injection point which is defined from measurements and calculations based on the monitoring of voltage values in the electrodes of the slave laser and sweeping of parameters related to the operational conditions of the slave laser. The method of the invention hereby disclosed provides automatic and programmable signal generation from radiofrequency up to Terahertz frequencies, simultaneously providing low phase noise, high modulation bandwidth, wide frequency range and high frequency resolution.
