Low-loss SbS Optical Phase Shifter Enabled by Optimizing Sputtering Conditions
Yuto Miyatake, Tomohiro Anda, Yosuke Wakita +6
By quantitatively evaluating the atomic concentrations of sputtered SbS films with different sputtering powers and Ar flows, we reveal that a sputtered SbS film bec…
17 GHz Lossless InP-Membrane Active Metasurface
Taichiro Fukui, Kei Sumita, Hiroki Miyano +12
High-speed active metasurfaces enable spatiotemporal control of incident light within an ultra-thin layer, offering new possibilities for optical communication, computing, and sens…
Si-waveguide-based optical power monitoring of 22 Mach$\unicode{x2013}$Zehnder interferometer based on InGaAsP/Si hybrid MOS optical phase shifter
Tomohiro Akazawa, Stéphane Monfray, Frédéric Boeuf +3
Transparent in-line optical power monitoring in Si programmable photonic integrated circuits (PICs) is indispensable for calibrating integrated optical devices such as optical swit…
Non-volatile optical phase shift in ferroelectric hafnium zirconium oxide
Kazuma Taki, Naoki Sekine, Kouhei Watanabe +6
A non-volatile optical phase shifter is a critical component for enabling large-scale, energy-efficient programmable photonic integrated circuits (PICs) on a silicon (Si) photonics…
Breakdown-limited endurance in HZO FeFETs: mechanism and improvement under bipolar stress
Kasidit Toprasertpong, Mitsuru Takenaka, Shinichi Takagi
Breakdown is one of main failure mechanisms that limit write endurance of ferroelectric devices using hafnium oxide-based ferroelectric materials. In this study, we investigate the…
