A recent innovation in diamond technology involves the development of black diamonds (BD), which have high optical absorption due to processing with a femtosecond laser. This study investigates the optical behavior of BD samples and demonstrates a near zero dielectric permittivity under high electric field conditions, exhibiting the Frenkel-Poole effect. The discovery of such zero-epsilon materials (ENZ) is expected to significantly advance integrated photonic devices and optical interconnections, leading to the development of novel functional photonic devices based on BD.
A recent innovation in diamond technology has been the development of the black diamond (BD), a material with very high optical absorption generated by processing the diamond surface with a femtosecond laser. In this work, we investigate the optical behavior of the BD samples to prove a near to zero dielectric permittivity in the high electric field condition, where the Frenkel-Poole (FP) effect takes place. Zero-epsilon materials (ENZ), which represent a singularity in optical materials, are expected to lead to remarkable developments in the fields of integrated photonic devices and optical interconnections. Such a result opens the route to the development of BD-based, novel, functional photonic devices.
