SHORT OPTICAL PULSE GENERATOR, TERAHERTZ WAVE GENERATION DEVICE, CAMERA, IMAGING APPARATUS, AND MEASUREMENT APPARATUS

摘要

A short optical pulse generator which includes an optical pulse generation portion that has a quantum well structure and generates an optical pulse, a frequency chirp portion that has a quantum well structure and chirps a frequency of the optical pulse, and a group velocity dispersion portion that includes a plurality of optical waveguides disposed in a mode coupling distance and which causes a group velocity difference corresponding to a wavelength in the optical pulse of which the frequency is chirped.
