Abstract: PURPOSE: A method for manufacturing a tapered waveguide is provided to reduce the manufacturing process and control a shape of the waveguide accurately by using a gray scale mask. CONSTITUTION: An under-clad layer(32) and a core layer are sequentially deposited on a substrate(31). A photoresist is applied on the core layer and exposed using a gray scale mask. A desired photoresist profile is obtained by adjusting an ultraviolet transmittance of the gray scale mask. A photoresist pattern is formed through exposing and developing processes. The photoresist pattern and the core layer are etched through a dry-etching process to form a core pattern(33'). A taper is formed on the core pattern(33'). After applying a photoresist on the core pattern(33') on which the taper is formed, a photoresist mask pattern(35) is formed in order to manufacture a waveguide having a horizontal taper through a lithography process. The waveguide is formed by etching a lower-core layer using the photoresist mask pattern(35) as a mask, and then an over-clad layer is deposited.
