Method of manufacturing optical multiplexer and optical multiplexer manufactured thereby

Abstract

An optical multiplexer (MUX) according to an embodiment of the present disclosure includes a base part having a plate-shape having a first surface and a second surface opposite to the first surface, a microarray lens layer integrally formed on the first surface of the base part, the microarray lens layer including microlens layers being multiple aspherical surface-shaped, and multiple optical blocks integrally formed on the second surface of the base part and formed at respective positions corresponding to the microlens layers.

What is claimed is: 
     
         1 . An optical multiplexer (MUX) comprising:
 a base part having a plate-shape having a first surface and a second surface opposite to the first surface;   a microarray lens layer integrally formed on the first surface of the base part, the microarray lens layer comprising microlens layers being multiple aspherical surface-shaped; and   multiple optical blocks integrally formed on the second surface of the base part and formed at respective positions corresponding to the microlens layers.   
     
     
         2 . The optical MUX of  claim 1 , wherein each of the optical blocks includes a first surface forming a right angle to the base part and a second surface formed at a predetermined angle to the first surface of the optical block, such that the optical block has a right triangle shape in vertical section; and
 different filter layers are formed on the respective second surfaces of the optical blocks.   
     
     
         3 . The optical MUX of  claim 2 , wherein the multiple optical blocks comprising a first optical block of which a first surface is located at an outermost side of the multiple optical blocks, and the first optical block includes an aspherical lens layer formed in the first surface thereof.
