International audienceThis Letter introduces the design and simulation of a microstrip-line-based electro-optic (EO) polymer opticalphase modulator (PM) that is further enhanced by the addition of photonic crystal (PhC) structures that are inclose proximity to the optical core. The slow-wave PhC structure is designed for two different material configurationsand placed in the modulator as a superstrate to the optical core; simulation results are depicted for both1D and 2D PhC structures. The PM characteristics are modeled using a combination of the finite elementmethod and the optical beam propagation method in both the RF and optical domains, respectively.The phase-shift simulation results show a factor of 1.7 increase in an effective EO coefficient (120 pm/V) whilemaintaining a broadband bandwidth of 40 GHz
