OPTICAL MODULE FOR SIMULTANEOUSLY SUPPRESSING LIGHT AND ELECTRIC CROSS TALK

摘要

PURPOSE: An optical module is provided to simultaneously suppress a light and crosstalk by forming a cut-off trench to isolate the light and the electromagnetic wave between the active devices. CONSTITUTION: An optical module for simultaneously suppressing a light and crosstalk includes a substrate(100), a plurality of mount trenches(106a,106b), a cut-off trench(107) and a metal wall. The plurality of mount trenches(106a,106b) which are formed in the substrate(100) mount a plurality of active devices(104a,104b) on the substrate(100). The cut-off trench(107) which is formed in the plurality of mount trenches(106a,106b) isolates the light and the electromagnetic waves. And, the metal wall which is formed in the cut-off trench(107) isolates the light and the electromagnetic waves.
