Photonic implementation of artificial synapses in ultrafast laser inscribed waveguides in chalcogenide glass
Simple and direct prototyping methods are ideal for large-scale delivery of cognitive photonic hardware. Here, we choose ultrafast laser writing as a direct fabrication technique to later demonstrate all-optical synaptic-like performance along the laser-written waveguides in a chalcogenide glass. Ne...
