Abstract

We describe and demonstrate experimentally a method for photonic mixing of microwave signals by using a silicon electro-optical Mach–Zehnder modulator enhanced via slow-light propagation. Slow light with a group index of ∼11, achieved in a one-dimensional periodic structure, is exploited to improve the upconversion performance of an input frequency signal from 1 to 10.25 GHz. A minimum transmission point is used to successfully demonstrate the upconversion with very low conversion losses of ∼7  dB and excellent quality of the received 퐼/푄 modulated QPSK signal with an optimum EVM of ∼8%.
