In this thesis, we studied chirp response and slow light properties in strained saturable Bragg reflector (SSBR). In the part of chirp response studying, we simulated the chirp response of SSBR of pulses with different chirps, and verified the results of related work. The trend of simulation was consistent with experimental result. Therefore firmly believing the broadening or compression ability of chirped incident pulse in SSBR, the pulse compression ability facilitates the mode-locking in laser cavity and generates more narrow pulse. In the studying of slow light properties in SSBR, a home-made pulse shaper system and a cross-correlator system were demonstrated. We control the chirp of the pulse by pulse shaper, and then pulse enter SSBR and reflect from SSBR, and measure the signal distribution in time domain by cross-correlator, finally we can analyze the properties of slow light of SSBR. We have demonstrated the slow light phenomenon was observed as central wavelength of incident pulse approach to resonance absorption of SSBR. In the aspect of chirp control, contrast with negative chirped incident pulse, slower group velocity with larger group delay for positive chirped incident pulse was observed. This could be attributing to absorption increasing which result from more efficient for creating carrier and less-sensitive to the carrier-scattering effect. In addition, we further study power dependence of slow light properties in SSBR under various incident chirps. Increasing group delay with power of incident pulse was performed. In addition, more group delay under saturation was also characterized and analyzed.
