PACKAGE STRUCTURE OF AN OPTICAL MODULE

摘要

This invention relates to a package structure of an optical module. A light emitting and light receiving chips are disposed on a light emitting and light receiving region of the substrate, respectively. Two encapsulating gels cover the light emitting chip and the light receiving chip, respectively, and form a first and a second hemispherical lens portions on the light emitting chip and the light receiving chip, respectively. A cover is affixed on the substrate and each of the encapsulating gels and has a light emitting hole and a light receiving hole, wherein the first and the second lens portions are accommodated, respectively. An engaging means is formed on an adjacent surface between each encapsulating gels and the cover in a horizontal direction. Thereby, the package structure of the optical module of the present invention increases the connection region between each encapsulating gels and the cover to enhance the engagement.
