SURFACE EMITTING LASER DIODE AND METHOD FOR MANUFACTURING IT

摘要

PURPOSE: A surface emitting laser diode and a manufacturing method thereof are provided to improve current inflow efficiency by forming the top electrode at the top center of an active layer between the first and the second reflection layers. CONSTITUTION: An active layer(123) formed on a plate(100) generates a laser beam. Bottom and top reflection base layers(122,127) resonate the laser beam by reflecting it. The top reflection base layer(127) comprises a first reflection base layer(127a) and a second reflection base layer(127b). A top electrode(130) is deposited on the top of the first reflection base layer(127a) excluding the top center region(123a) of an active layer(123). The second reflection base layer(127b) of the top reflection base layer(127) is formed on the part of the first reflection base layer(127a) and the top electrode(130).
