Outline of Final Research Achievements

High repetition rate short optical pulses generation technique from a CW LD based on electro-optic modulators have been developed. A wide repetition rate tunable range of 18-28 GHz and a wide wavelength tunable range of 1530-1575 nm could be achieved while keeping the pulse duration shorter than 0.5 ps. From the numerical simulation results, we have clarified that sub-10-fs pulse duration could be achieved by using a progressive expansion of the spectrum in the self-phase modulation process in an erbium-doped fiber amplifier if we use a broadband optical amplifier. The demonstration of the dual-comb spectroscopy and the ultralow-phase-noise millimeter-wave signal generation which is superior to commercially available signal generators are also succeeded by using our developed optical source.
