Agulto V, Iwamoto T, Zhao Z, Liu S, Kato K, Nakajima M
Opt Lett . 2025 Jan; 50(3):948-951. PMID: 39888794
Terahertz (THz) measurements are increasingly valued for nondestructive testing of materials in power devices and other applications. Hence, there is a growing demand for highly accurate characterization methods in the...

Khoa Phan T, Wang Y, Shimizu T, Kato K, Agulto V, Isoyama G, et al.
Opt Lett . 2024 Sep; 49(18):5039-5042. PMID: 39270224
The nonlinear susceptibility in the terahertz region is expected to have a non-negligible imaginary part originating from the momentum-dependent scattering time of free carriers, but it has been scarcely reported....

Akabe Y, Shinohara K, Cadatal-Raduban M, Yoshikawa A, Shimizu T, Kato K, et al.
Opt Lett . 2024 Jul; 49(14):3998-4001. PMID: 39008761
We propose a system for imaging 1510 nm near-infrared (NIR) wavelength via upconversion (UC) luminescence in an Er-doped CaF crystal. Er ions are excited from the ground to the excited...

Wang J, Cai W, Lu W, Lu S, Kano E, Agulto V, et al.
Nature . 2024 Jun; 631(8019):67-72. PMID: 38839970
Since the demonstration of p-type gallium nitride (GaN) through doping with substitutional magnesium (Mg) atoms, rapid and comprehensive developments, such as blue light-emitting diodes, have considerably shaped our modern lives ...

Khoa Phan T, Tomoki S, Wang Y, Kato K, Agulto V, Isoyama G, et al.
Opt Lett . 2024 Feb; 49(4):1073-1076. PMID: 38359256
We report on the third harmonic generation (THG) in InSb semiconductor irradiated by a terahertz (THz) free electron laser (FEL). The conversion of 4 THz (wavelength 70 µm) FEL outputs...

Agulto V, Ling Z, Zhao Z, Feng S, Kato K, Haga M, et al.
Opt Lett . 2023 Dec; 48(23):6324-6327. PMID: 38039258
The development of electromagnetic wave absorbers operating in the sub-terahertz (sub-THz) region is necessary in 6G communications. We designed and fabricated a sub-THz metamaterial absorber based on metal microcoils embedded...

Nakajima H, Uchida K, Yoshida T, Horii Y, Sato T, Luming Z, et al.
Chemphyschem . 2022 Oct; 24(4):e202200618. PMID: 36287210
We report the water adsorption/desorption behavior and dynamic magnetic properties of the Pt-Cl chain complex [{[Pt(en) ][PtCl (en) ]} ][{(MnCl )Cl } ] ⋅ 12H O (1). Upon heating 1...

Iba A, Ikeda M, Agulto V, Mag-Usara V, Nakajima M
Sensors (Basel) . 2021 Oct; 21(20). PMID: 34695944
This paper describes the design and development of a cylindrical super-oscillatory lens (CSOL) for applications in the sub-terahertz frequency range, which are especially ideal for industrial inspection of films using...

Agulto V, Iwamoto T, Kitahara H, Toya K, Mag-Usara V, Imanishi M, et al.
Sci Rep . 2021 Sep; 11(1):18129. PMID: 34526558
Gallium nitride (GaN) is one of the most technologically important semiconductors and a fundamental component in many optoelectronic and power devices. Low-resistivity GaN wafers are in demand and actively being...
