Liquid powered and cooled microfluidics photonics architecture

A device comprising:

• a substrate;
• an electrical load supported by the substrate;
• a microfluidic volume positioned in the substrate;
• a first electrode positioned in the microfluidic volume;
• a second electrode positioned in the microfluidic volume;
• a first through silicon via (TSV) connecting the first electrode to the electrical load;
• a second TSV connecting the second electrode to the electrical load;
• and
• an electrochemical fluid positioned in the microfluidic volume to provide electrical power to the electrical load and receive heat from the electrical load.

A method of powering and cooling a photonics in an electronic device, the method comprising:

• flowing a working fluid through a microfluidic volume of a substrate proximate a waveguide;
• receiving heat generated by a photonic signal in the waveguide with a working fluid to create hot working fluid;
• exhausting the heat from the working fluid to create cold working fluid;
• and
• recirculating the cold working fluid into the substrate.
