Volumetric Optical Integrated Circuit Elements (V.O.I.C.E.)

The fabrication of mulitple plans of interconnected passive photonic devices with the volume of a silicon wafer. This fabrication technique uses porous silicon as a scaffold for photoresist in a direct laser write process to make graded index (GRIN) optics and photonic elements. This technology will dramatically improve the speed, denistiy, and energy efficiency in applications like telecommunications, computing, data storage and transfer and consumer electronics.
