Useless. What this tells me is that, until today, you had no idea what hurdles plasmonics needed to overcome.
From one source cited - ". Furthermore, silicon photonics platforms have successfully leveraged advancements in heterogenous integration of light sources using methods such as waferbonding, flip-chip bonding, and micro-transfer printing to integrate emerging photonic IC technologies based on materials like Graphene, Ferroelectrics, Plasmonics, and others."
