Abstract

The present invention relates to a substrate for an optical device, which is configured to connect an optical element substrate and an electrode substrate in a fitting manner, and simultaneously, to form one or more bridge pads which are insulated from the optical element substrate by a horizontal insulating layer, on the optical element substrate. The substrate for an optical device according to a first aspect of the present invention comprises: an optical element substrate which is made of a metal plate and contains a plurality of optical elements therein; a pair of electrode substrates which are made of an insulating material to form a conductive layer on at least a portion of the upper surface thereof, are connected to both side surfaces of the optical element substrate, respectively, and are wire-bonded to the electrodes of the optical elements; and a fitting means which is formed on the side surfaces of the electrode substrate and the optical element substrate to fit the optical element substrate and the electrode substrate. The substrate for an optical device according to a second aspect of the present invention comprises: an optical element substrate which is made of a metal plate and contains a plurality of optical elements therein; a pair of electrode substrates which are made of a metal material to be connected to both side surfaces of the optical element substrate, respectively, and are wire-bonded to the electrodes of the optical elements; a fitting means which is formed on the side surfaces of the electrode substrate and the optical element substrate to fit the optical element substrate and the electrode substrate; and a fitting-type vertical insulating layer which is interposed between the optical element substrate and the electrode substrate so as to be connected to the fitting means.
