Substrate-Voltage-Controlled Temporal Nonlinearity in Ferroelectric FET-based Reservoir Computing
Eishin Nako, Ryosho Nakane, Mitsuru Takenaka +2
Physical reservoir computing exploits inherent nonlinearity and short-term memory of physical dynamics to achieve efficient processing of time-series data with extremely-low traini…
Memory Window in Ferroelectric Field-Effect Transistors: Analytical Approach
Kasidit Toprasertpong, Mitsuru Takenaka, Shinichi Takagi
A memory window of ferroelectric field-effect transistors (FeFETs), defined as a separation of the HIGH-state and the LOW-state threshold voltages, is an important measure of the F…
Non-volatile hybrid optical phase shifter driven by a ferroelectric transistor
Rui Tang, Kouhei Watanabe, Masahiro Fujita +5
Optical phase shifters are essential elements in photonic integrated circuits (PICs) and function as a direct interface to program the PIC. Non-volatile phase shifters, which can r…
Ultrahigh-sensitivity optical power monitor for Si photonic circuits
Takaya Ochiai, Kei Sumita, Shuhei Ohno +5
A phototransistor is a promising candidate as an optical power monitor in Si photonic circuits since the internal gain of photocurrent enables high sensitivity. However, state-of-t…
