Kaunga-Nyirenda, S.N. and Dias, H.K. and Lim, J.J. and Bull, S. and Malaguti, S. and Bellanca, G. and Larkins, E.C. (2014) Design and simulation of high-speed nanophotonic electro-optic modulators. In: Numerical Simulation of Optoelectronic Devices, 2014, 1-4 September 2014, Palma de Mallorca.
In this work, an ultracompact electro-optic modulator based on refractive index modulation by plasma dispersion effect in PhC all-optical gate (AOG) is proposed. The index modulation is achieved by applying a time-varying bias voltage across the electrical contacts of the AOG. The proposed modulator has potential for high-speed operation, with bandwidths in excess of 30GHz achievable.
