The optical losses in photonic crystal laser cavities were investigated by varying the number of lattice periods. The threshold pump power increased from 1.53 mW to 2.74 mW when the number of periods decreased from eleven to nine. The lasing wavelength was expected to shift to shorter wavelengths where there was more available gain as the number of periods decreased.
