Abstract

<p>LiNbO3 electro-optic (EO) modulators are widely used in long-haul optical fiber communication systems and microwave photonic systems owing to the excellent modulation characteristics of high speeds, broad bandwidth, high stability, and good reliability. In particular, LiNbO3 modulators enable us to control the amplitude and phase of a lightwave precisely at a high-speed since unwanted frequency chirping in the optical modulation is extremely small. Now, LiNbO3 vector modulators using a double Mach-Zehnder waveguide are a prerequisite for advanced high-density data transfer techniques. In addition, LiNbO3 is categorized as a ferro-electric crystal with relatively large spontaneous polarization. Recently, techniques to reverse the direction of spontaneous polarization in LiNbO3 crystals have been developed and applied to high-efficiency nonlinear optical devices for light wavelength conversion. By utilizing the polarization reversal techniques with LiNbO3 EO modulators, new advanced function devices are obtainable. In this paper, recent studies on EO devices utilizing polarization-reversed structures and their possibility for new applications are discussed.</p>
