Optical module and method for manufacturing the same

A method for manufacturing an optical module comprising the steps of:

• first etching to form one or more grooves on a first surface of a wafer;
• and
• second etching to form one or more stopper holes so that the first surface of the wafer is etched to penetrate the wafer or is etched to a predetermined depth.

An optical module having a substrate, a V-groove for mounting an optical fiber on the substrate, a micro-pit for mounting optical parts, and a hole for assembling an actuator, the optical module comprising:

• a first stopper hole formed to communicate with the V-groove and the micro-pit, in which the substrate is penetrated in a vertical direction;
• and
• a second stopper hole formed to communicate with the micro-pit and the hole, in which the substrate is penetrated in a vertical direction.

An optical module having one or more grooves for mounting one or more optical parts on a substrate, wherein the optical module includes stopper holes which are formed by penetrating the bottom surface of the substrate which corresponds to a predetermined region among the grooves.

A method for manufacturing an optical module comprising the steps of:

• first etching to form one or more stopper holes so that the bottom surface of a wafer is etched to penetrate the wafer;
• and
• second etching to form one or more grooves for mounting optical elements on the top surface of the wafer.
