By properly adjusting the positive coefficient of thermal expansion of the polymer substrate and the negative thermo-optic coefficient of the polymer waveguide, athermal and polarisation-in-dependent AWG devices are demonstrated.enintegrated opticsmultiplexing equipmentoptical arraysoptical communication equipmentoptical polymersoptical waveguidesthermal expansionthermo-optical effectsathermal polarisation-independent arrayed waveguide grating multiplexerall-polymer approachpositive coefficientpolymer substratenegative thermo-optic coefficientpolymer waveguidepolarisation independent awg devices621journal article
