Abstract
A compact apparatus and a method for generating wavelength-tunable short optical pulses, which apparatus and method can change the wavelength of generated pulses without adjustment of an optical system and enable generation of ideal femtosecond soliton pulses. The apparatus includes a short-optical-pulse source, an optical characteristic regulation unit for regulating characteristics of light output from the short-optical-pulse source, and an optical fiber for receiving input pulses from the optical characteristic regulation unit and for changing the wavelength of output pulses linearly. Short optical pulses are input to the optical fiber, so that new soliton pulses are generated in the optical fiber due to its nonlinear effect. Further, the nonlinear effect enables the wavelength of the soliton pulses to shift linearly in accordance with the intensity of input light.
