Recent progresses in optical modulation using electro-optic effects have renewed photonic signal processing technologies crucial in future advanced optical communication systems. NICT is now exploring novel functional photonic devices and subsystems based on electro-optic modulation technologies. In this paper, we review on recent research activities in NICT around these exotic technologies, picking up following three topics: (1) optical modulator array with patch antennas for weak radio-wave detection, (2) optical ring filter based on Ti-diffused LiNbO3 waveguide loop for high efficient modulation, (3) photonic-electronic oscillator for self-oscillating optical comb generation.
