Gịnị bụ micro-nano Photonics?

Micro-nano photonics mainly studies the law of interaction between light and matter at micro and nano scale and its application in light generation, transmission, regulation, detection and sensing. Ngwaọrụ micro-Nano Photonics nwere ike ime ka ogo ogo Photon melite ogo njikọta, a na-atụ anya itinye ngwaọrụ na-agbakọta na obere mgbawa dị ka ibe hookrọniki dị ka ibe elektrọnik.
