Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that only the direct modulation of 2.5Gbit/sec can be realized at the best in a device employing a conventional type-I structure dots wherein electrons and holes are confined to the same material since carrier relaxation rate between discrete energy levels is controlled by the phonon bottle neck phenomenon.  <P>SOLUTION: In the optical semiconductor device, a quantum dots having so-called type-II structure wherein respective quantum dots for confining electrons and holes are formed of separate materials. In the type-II structure, an interval between respective discrete energy levels of the electron and the hole can be optimized separately by the composition of a material and the size of the dot. Accordingly, both of the carriers can be relaxed to the ground level in respective quantum dots at a high speed. An optical semiconductor device having very small chirping (dynamic fluctuation in time) is obtained. Representative examples of the optical semiconductor device are a semiconductor laser device, an optical amplifier or the like. According to this method, the semiconductor laser device which permits direct modulation by current while maintaining a very low chirping is obtained. Furthermore, the optical amplifier, very much reduced in the crosstalk between wavelengths while maintaining the very low chirping, is obtained.  <P>COPYRIGHT: (C)2004,JPO
