SUBSTRATE FOR AN OPTICAL DEVICE HAVING A ZENER DIODE

WIPO Patent Application WO/2013/009081

A3

The present invention relates to a substrate for an optical device having a zener diode, in which an optical element and the zener diode are accommodated in separate cavities so as to minimize optical interference caused by the zener diode, and in which a vertical insulation layer is used such that there is no need for a patterning process for an electrode or a signal line and that time needed for wire bonding is minimized. The substrate for the optical device having the zener diode according to the present invention consists essentially of: two or more columns of substrates each having a conductive upper surface, wherein vertical insulating layers are vertically interposed therebetween so as to electrically insulate the substrates; the cavity for the optical element, made of grooves formed on the upper portions of the substrates of every two adjacent columns so as to contain the vertical insulation layers; the cavity for the zener diode, made of grooves formed on the upper portions of the substrates of every two adjacent columns to contain the vertical insulation layers; and the optical element and the zener diode which are accommodated in the cavity for the optical element and in the cavity for the zener diode, respectively, such that an electrical connection between the optical element and the zener diode is in a reverse direction.
