Optical power transfer devices with an embedded active cooling chip

An optical power transfer device comprising:

• a first cooling chip and a second cooling chip positioned opposite to the first cooling chip, each cooling chip made of a semiconductor material and comprising:
• at least one metallization layer on a portion of a first surface of the cooling chip;
• at least one inlet through a second surface of the cooling chip, wherein the second surface is opposite to the first surface;
• at least one outlet through the second surface;
• and
• one or more micro-channels extending between and fluidly coupled to the at least one inlet and the at least one outlet, the one or more micro-channels having a cooling fluid flowing therethrough;
• a first subassembly mounted on the at least one metallization layer on the first cooling chip, the first subassembly comprising a laser;
• and
• a second subassembly mounted on the at least one metallization layer on the second cooling chip, the second subassembly comprising a phototransducer configured to receive a laser beam from the laser.
