To provide a semiconductor short pulse generating device, a terahertz-wave generating device, a camera, an imaging device, and a measuring device which have high utilization efficiency of light and do not require a complicated manufacturing process.
The a semiconductor short pulse generating device comprises: an optical pulse generating section 2 for generating an optical pulse; a first pulse compression section 3 for compressing the optical pulse which has been generated in the optical pulse generating section 2 based on saturable absorption; a second pulse compression section 5 for compressing the optical pulse which has been compressed in the first pulse compression section 3 based on group velocity dispersion compensation; and an amplification section 4 which is provided on the front stage of the first pulse compression section 3 or between the first pulse compression section 3 and the second pulse compression section 5, and amplifies the optical pulse. The optical pulse generating section 2 is a super luminescent diode.
