LONG WAVELENGTH SURFACE EMISSION TYPE OF LASER AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A long wavelength surface emission type of laser and a method for manufacturing the same are provided to form an air layer having same effect as an oxide layer using a wet etching method without using the oxide layer in forming a current confinement aperture. CONSTITUTION: In a long wavelength surface emission type of laser and a method for manufacturing the same, the long wavelength surface emission type of laser has an under mirror layer(6) formed on a substrate, an air post patterned resonate layer formed on the under mirror layer and an upper mirror layer(20). The under stage part of the upper mirror layer near the resonate layer has the air layer having a desired depth at the side wall of the upper mirror layer.
