Classification: CPC H  G | IPC G  H

Claim 19:
20. A method comprising:
manufacturing a low-voltage die that includes an array of light-emitting devices that are connected in parallel with one another and are configured to be powered via an electrical input;
manufacturing a high-voltage die that includes an array of photovoltaic cells that are connected in series with one another and are configured to produce an electrical output whose voltage is higher than the electrical input; and
forming a high-voltage optical transformer with the low-voltage die and the high-voltage die by:
bonding a transfer medium between the low-voltage die and the high-voltage die; and
optically coupling the array of light-emitting devices to the array of photovoltaic cells via the transfer medium.
