Nanophotonic integrated circuit and fabrication thereof

摘要

A class of nanophotonic integrated circuit (nPIC) has been disclosed that is a platform technology for fiberoptic communication and computing, that is fabricated from waveguides that are based on natural index contrast (NIC) principle. A multifunctional nPIC and its fabrication details have been described. The nPIC is also known as an “optical processor”. A novel nanomaterial “dendrimer” is highlighted as the key ingredient that enables the fabrication of the nPICs and its multifunctionality from the same basic process. Other nanomaterials such as spin-on glass, nano-silica sol, and a combination of any of these materials can also be used via the natural index contrast method. Several preferred embodiments of the nPIC are described.
