Design and experimental demonstration of photonic-crystal lasers with multijunction active layers
Shumpei Katsuno, Masahiro Yoshida, Takuya Inoue +4
We introduce multijunction active layers, featuring a stack of alternating active layers and tunnel junctions, to PCSELs to increase their slope efficiency, which is vital for vari…
Demonstration of high-power photonic-crystal surface-emitting lasers with 1-kHz-class intrinsic linewidths
Ryohei Morita, Takuya Inoue, Masahiro Yoshida +4
Photonic-crystal surface-emitting lasers (PCSELs) are capable of single-mode, high-power lasing over a large resonator area owing to two-dimensional resonance at a singularity poin…
Unidirectional perfect reflection and radiation in double-lattice photonic crystals
Takuya Inoue, Naoya Noguchi, Masahiro Yoshida +3
Non-Hermitian photonic systems are known to exhibit unique phenomena, where non-Hermiticity is typically introduced by material loss or gain. Here, we propose and experimentally de…
Gate-controlled generation of optical pulse trains using individual carbon nanotubes
M. Jiang, Y. Kumamoto, A. Ishii +3
We report on optical pulse-train generation from individual air-suspended carbon nanotubes under an application of square-wave gate voltages. Electrostatically-induced carrier accu…
Stark effect of excitons in individual air-suspended carbon nanotubes
M. Yoshida, Y. Kumamoto, A. Ishii +2
We investigate electric-field induced redshifts of photoluminescence from individual single-walled carbon nanotubes. The shifts scale quadratically with field, while measurements w…
