Abstract
A manufacturing method of a vertical cavity surface emitting laser is provided. The vertical cavity surface emitting laser includes a first reflector, a first semiconductor layer, an active layer, a second semiconductor layer, an oxide layer, and a second reflector sequentially stacked. The conductivity type of the first semiconductor layer is opposite to that of the second semiconductor layer. The oxide layer includes a light transmitting region and a light shielding region, and the light shielding region surrounds the light transmitting region. The manufacturing method includes planarizing a first contact surface of the first semiconductor layer and the first reflector, and/or a second contact surface of the second semiconductor layer and the second reflector.
