Abstract
Voltage is applied between electrodes ( ) under UV irradiation to perform a UV excitation poling, thereby producing microcrystal particles at a core unit ( ). Accordingly, second-order optical nonlinearity is developed at the core unit ( ) of an optical fiber ( ). Under a high-temperature condition, a second-order optical nonlinearity can be imparted by a comparatively low-voltage UV excitation poling when a second-order optical nonlinearity decreases.
