Step Towards Light-Based, Brain-Like Computing Chip

Scientists have succeeded in developing a piece of hardware which could pave the way for creating computers resembling the human brain. They produced a chip containing a network of artificial neurons that works with light and can imitate neurons and their synapses. This network is able to โ€learnโ€ information and use this as a basis

Changing the Color of Light

One of the biggest challenges in developing integrated photonic circuits โ€” which use light rather than electrons to transport information โ€” is to control the momentum of light. Colors of light travel at different speeds through a material but in order for light to be converted between colors, it needs to have the same momentum

Programmable Nanophotonic Processor Allows Optical Deep Learning

โ€œDeep learningโ€ computer systems, based on artificial neural networks that mimic the way the brain learns from an accumulation of examples, have become a hot topic in computer science. In addition to enabling technologies such as face- and voice-recognition software, these systems could scour vast amounts of medical data to find patterns that could be
