The gain coefficient of a GaAs-AlGaAs single-quantum-well laser in an applied static electric field is calculated. The quasi-bound-state energy and the lifetime are obtained by using the tunneling resonance technique. The principal field effects on the laser emission are (i) shift of the laser wavelength, (ii) reduction and broadening of the gain spectrum, and (iii) increase of the threshold current. Based on the field-dependent shift of the peak gain position, a possible wavelength tuning mechanism for the quantum-well laser is proposed.
