Nanophotonic Logic Gates

Objective

The objective of PHOLOGIC project is to explore the mass-manufacturing compatibility of non-linear photonic materials (CdTe and Si nanocrystals) and their associated fabrication processes with CMOS processing lines using a highly scalable photonic logic gate structure as functional validation device. For the sake of benchmarking a third technological approach based on InP planar photonic crystals is also addressed.

The CdTe and Si-nc materials show excellent nonlinear features and their fabrication processes can be incorporated in an intermediate step within a CMOS processing line. The full optical characterisation of the materials and the optimisation of their fabrication processes will be carried out in the PHOLOGIC project, which will suppose a radical long-term innovation beyond current state-of-the-art and a clear innovation aimed at mastering nanophotonics for low cost.

As a functional validation device an all-optical logic gate using a non-linear Mach-Zehnder interferometer structure will be implemented offering key features for mass-manufacturing such as a high scalability and flexibility to implement advanced functional devices. Furthermore, photonic crystals as well as other periodic structures will be used to exploit the concept of slow wave-guiding reducing thus the size and power requirements of the all-optical logic gate.

A monolithic all-optical logic gate on InP based on a buried heterostructure integrating photonic crystals will also be produced for the first time in order to improve the degree of integration and to be used as a benchmarking action with respect to the other two technological approaches (CdTe and Si-nc). The technical assessment among the three proposed technological approaches will be carried by a Consultation Panel formed by several important companies (Si mass-manufacturers, equipment producers and foundries) that will provide evaluation and recommendations in terms of mass-manufacturing, reliability and optical performance.
