Abstract: PURPOSE:To enable the oscillation light rays of a semiconductor light emitting device to be lessened in spectral line width by a method wherein an active layer is of a quantum well structure, and a wavelength selection means selects wavelengths correspondent to the second quantum level energy of the quantum well. CONSTITUTION:A prescribed bias is applied to a P-side electrode 15 and an N-side electrode 16, and a current is injected into a QW active layer 13 to oscillate laser rays.

When carriers distributed at an energy E2 start to recombine, a differential gain becomes large and a refractive index change attendant on that of carrier density becomes small. Therefore, in this state, an alpha parameter becomes small at a second quantum level energy E2.
