Modal evolution of induced second-harmonic light in an optical fiber.
We show how the mode of the photoinduced second-harmonic light in an optical fiber changes with preparation time. We also discuss what type of nonlinear interaction can be causing the induced second-harmonic light and give experimental evidence that the initial second-harmonic light is a core-cladding interface effect.
