P-substrate buried crescent (PBC) laser diodes whose wavelength ranged from 1.2 to 1.55-mu-m have been fabricated. The threshold currents as low as 10 mA have been obtained in this wavelength range experimentally. The calculated threshold currents of 13, 13, and 14 mA at 1.2, 1.3, and 1.55-mu-m almost coincide with the measured values.
