Reactive metal optical security device and methods of fabrication and use

A secure system for an optical transmission pathway, the system comprising:

• a computer system configured to generate data;
• an optomodulator configured to output the data;
• an optical bus configured to receive the output data;
• a first mirror positioned at a first end of the optical pathway in an optical network and/or system, the first mirror comprising a first metal stack comprising:
• a first reflective metal that is configured to face the optical bus;
• a first base metal;
• and
• a first dielectric configured to be electrically broken down, wherein the first dielectric separates the first reflective metal from the first base metal;
• a second mirror positioned at a second end of the optical pathway in the optical network and/or system, the second mirror comprising a second metal stack comprising:
• a second reflective metal that is configured to face the optical bus;
• a second base metal;
• and
• a second dielectric configured to be electrically broken down, wherein the second dielectric separates the second reflective metal from the second base metal;
• a plurality of capacitors configured to store an electrical charge;
• and
• a voltage impulse generator coupled to the plurality of capacitors and configured to convey the electrical charge to the first mirror upon receiving a signal indicating a security compromise of the optical network and/or system,
• wherein the first metal stack of the first mirror has a workfunction difference that is sufficient to sustain a chemical reaction when the first dielectric is electrically broken down such that the first reflective metal is substantially or completely consumed by the chemical reaction upon receipt of the electrical charge when the system senses the security compromise.
