Abstract

Abstract: This paper shows that mapping of phase levels of a digitally modulated wireless signal from the mmWave domain to the equivalent optical domain is inherently a non-linear phenomenon in Pockel's effect-based seamless digital mmWave-to-photonic converters. We report several novel implications of seamless phase mapping, crucial for the realization of seamless wireless-to-photonic links. The latency and design complexity of such converters are expected to be appreciably lower than conventional converters. The results on seamless phase mapping presented in this paper are scalable with the wireless frequency of operation.
