In this work, we have proposed electro-optical nonlinear delayed feedback systems (NDFS) using VCSEL. NDFS is composed by non-linear function unit, a transfer function unit, a gain adjusting unit and delay elements unit. In this system, with the incr

We have experimentally demonstrated a new smart grid model which can control DC electric power flow autonomously among individual homes, by using an optical self-organized node with optical non-linear characteristics, and these homes are assumed to b
