Abstract
Optical second-harmonic generation from a glass-clad fiber with an organic core crystal of 4-(N,N-dimethylamino)-3-acetamidonitrobenzene (DAN) is demonstrated. Phase matching was due to Čerenkov radiation. Linear and nonlinear optical properties of DAN, a fabrication technique of a crystal-cored fiber, and a focusing method of the generated second-harmonic wave are studied.
