Developed here are a set of technologies to enable all-optical seismometers for use in boreholes and other harsh environments where expensive electronics cannot be put at risk. Employing the approaches developed here, seismometers collect and route all data optically to a safe location where it .....

Requires less power than alternative methods. AC coupling eliminates DC power consumption Cost and complexity of production are reduced. Complex etching is unnecessary since AC coupling scheme does not require via etching. A high-speed interconnect with improved signal integrity.
