Title: Semiconductor laser element and semiconductor laser
Inventor: ISHIDA AKIHIRO
IPC: H01S5/343
Filed: 2001-05-23
Abstract: PROBLEM TO BE SOLVED: To provide an infrared semiconductor laser element that does not require complicated element structure, can be manufactured easily, and can be operated at room temperature. SOLUTION: Electrons are excited by a light from a valence band (not shown) to a subband of n=2. When the electrons makes transition to a base subband (n=1), the electrons emit a light, corresponding to the energy gap between the two subbands. Since the base subband has a wide-band width of about 200 meV, the electrons which shift from the subband of n=2 to the base subband move to a low-energy region in the base subband in a very short time. Consequently, population inversion state is easily realized between the subband of n=2 and base subband and the transition of electrons occurs continuously. When the light emitted by the transition of the electrons is resonated optically, laser light is emitted.
