Abstract
Proyiainmable pMorvc circles. ?t cotrltasi lo classical p-itcloivc r-tegraieii ciscu-ts (PIC), can lie confgwed at run-time ?o route light along different paths and perform different optical functions This is acccmpt shed by a mesh of interconnected waveguides that are coupled using electrically actuated tunable couplers and phase shiiters. Such a waveguide mesh can redef ine the comechvity between hmcltonsi bukhrej fckjcKs, but can also be configured into interferefretnc end resonant wavelength filters. Tine generic nature of such programmable PICs wi8 lowei the UireshoW to develop new applications based on photon-c chips, in a similar way as programmable electronics Conference Presentation
