Abstract

An optical integrated circuit device includes an electrically insulating substrate, an optical connection disposed at a boundary of the optical integrated circuit, and a first electrostatic discharge (ESD) protection structure in direct contact with and electrically coupled to the first waveguide. The optical connection includes a first waveguide. The first waveguide is disposed on the electrically insulating substrate and configured to transmit an optical signal. The first ESD protection structure is both electrically non-insulating and substantially optically transparent to the optical signal. An ESD diode including an anode and a cathode is electrically coupled to the first ESD protection structure. A ground connection is electrically coupled to the anode of the ESD diode.
