Paper Abstract

Emission of higher-order modes caused by spatial hole burning in a quantum dot (QD) laser is studied. The critical tolerable values of the structure parameters are discussed beyond which higher-order longitudinal modes can not oscillate. The higher the mode order, the narrower the range of allowed QD-size scatter for lasing of the mode. The higher the mode order, the denser the QD-ensemble and the longer the cavity should be for lasing of the mode. The output powers of the lasing modes are calculated versus the injection-current density from the solution of the rate equations.
