3 What are Photonic ICs (PICs)? Photonic Integrated Circuits (PICs) are devices on which several optical components are integrated; PICs are usually fabricated using a wafer-scale technology using substrates of silicon, silica or InP; Most PICs use waveguides to allow the realization of couplers, filters, power splitters, combiners and active elements with optical gain or attenuation; A PIC by itself is not a product! Interfacing with fibers or free-space Interfacing with electronics Thermal interfacing Mechanical support 11-Dec-18 Micronano Conference 2018 Our chips drive your business 3
