We theoretically investigate the effects of carriers supplied from a dopant in AlAs cladding layers of a current-driven photonic crystal laser diode. The high doping concentration of cladding layers reduces the resistance of the diode, which is advantageous for practical operation. Carriers, however, bring about light loss and degradation of characteristics. It is thus important to investigate the effect of carriers so as to determine the most suitable doping profile of the cladding layers. For some typical photonic crystal cavity resonators, we carry out light wave simulations and investigate changes in laser characteristics, such as threshold current, electric power consumption, and maximum operation frequency.
