To generate ultrashort pulse train at a high repetition rate, Zn was doped to the active region of distributed-feedback lasers. Increase in the differential gain and reduction of the carrier lifetime have been confirmed. The 3 dB bandwidth was increased to 16 GHz. The 14 ps single longitudinal mode optical pulse train at a repetition rate of 14 GHz was generated by gain-switched operation.

    The standard n-type dopant Ga is predicted to change its character from a shallow donor to a deep trap with increasing alloy composition x in Zn1-xMnxSe. As a result, Ga-doped Zn1-xMnxSe alloys should be n type for very small x, but not for Mn-rich material.

    The conduction mechanism in aluminum-doped zinc oxide has been studied. Structural investigation shows that crystallographic orientation as well as grain boundary scattering can be neglected. Based on the analysis of the Hall mobility, it has been found that scattering at neutral and ionized...
