PURPOSE: A laser diode and a method for manufacturing the laser diode are provided to previously prevent the leakage current generated during the formation of the single window structure, thereby further simplifying the process of forming the p-capping layer. CONSTITUTION: A laser diode includes a p-cladding layer(14), a ridge(17), a current block layer(18), a dielectric block layer(19) and a p-capping layer(20). The ridge(17) is formed along the top surface of the p-cladding layer(14). The current block layer(18) is formed on both sides of the ridge(17) and on the top surface of the p-cladding layer(14) with a height being similar to that of the ridge(17). The dielectric block layer(19) is formed on the edge portions of the ridge(17) and the current block layer(18). And, the p-capping layer(20) is deposited on the top surface of the ridge(17) and the current block layer(18) except for the dielectric block layer(19).
