Abstract
There is provided a semiconductor laser device including multiple-quantum wells of different widths that uses carrier redistribution to adjust the wavelength if light. The semiconductor laser device according to the present invention is fabricated by forming at least two groups of multiple-quantum wells on a semiconductor substrate, so that the carrier distribution within the multiple-quantum wells can be readjusted according to the variation of external environment, and thus the wavelength of light can be adjusted as well.
Claims11
A semiconductor laser device including multiple-quantum wells of different widths or ingredients which uses carrier redistribution to adjust a wavelength of light, comprising:
- a semiconductor substrate;
- and
- multiple-quantum wells fabricated on said semiconductor substrate, wherein a carrier distribution in said multiple-quantum wells can be readjusted according to a variation of external environment to determine a wavelength of light emitted from said multiple-quantum wells.
