We present detailed measurements of the Henry factor (linewidth enhancement factor) above and below threshold of a quantum dot laser. Modulation frequency and current dependence of the above-threshold method based on modulation experiments is shown.

We report the growth of self-organized InAs/Sb:GaAs quantum dots (QDs) on silicon (Si) substrate by Metal Organic Chemical Vapor Deposition (MOCVD). High density QDs aligned along [0-11] direction was obtained. These QDs exhibit ground state emission at 1.3 mum at room temperature (RT).

MOCVD grown self-assembled quantum dot using dilute nitrogen material system (GaInNAs) is presented for GaAs-based long wavelength VCSELs. Suppression of Coalescence and inhomogeneous broadening by incorporating nitrogen into dot structure is particularly discussed.

We achieved slow light of 8.3 pulses of a 12-ps pulse in a series cascade of QW-SOAs in a loop configuration. The linear relationship between the number of optical passes through the SOA and time delay is experimentally demonstrated.

We demonstrate that optical activity for the zeroth-order transmitted light is extraordinarily enhanced in metal and dielectric planar chiral nanogratings by plasmon or waveguide resonance. This method can be used for THz applications.
