ABSTRACT:
The present invention provides a technology for increasing the spectral width of semiconductor optical amplifiers, employing different separate confinement heterostructures (SCH's) so as to form non-identical multiple quantum wells such that the semiconductor photo-electronic devices have better temperature characteristics and more reliable modulation characteristics. If such a technology is used in the fabrication of semiconductor laser with a tunable wavelength, it is possible to achieve a large range of modulated wavelength, which is very useful in optical communication.
