Sub-nanometre resolution of atomic motion during electronic excitation in phase-change materials
Kirill V. Mitrofanov, Paul Fons, Kotaro Makino +16
Phase-change materials based on Ge-Sb-Te alloys are widely used in industrial applications such as nonvolatile memories, but reaction pathways for crystalline-to-amorphous phase-ch…
Localized guided-mode and cavity-mode double resonance in photonic crystal nanocavities
X. Liu, T. Shimada, R. Miura +3
We investigate the use of guided modes bound to defects in photonic crystals for achieving double resonances. Photoluminescence enhancement by more than three orders of magnitude h…
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…
Ultralow mode-volume photonic crystal nanobeam cavities for high efficiency coupling to individual carbon nanotube emitters
R. Miura, S. Imamura, R. Ohta +6
We report on high efficency coupling of individual air-suspended carbon nanotubes to silicon photonic crystal nanobeam cavities. Photoluminescence images of dielectric- and air-mod…
Optical control of individual carbon nanotube light emitters by spectral double resonance in silicon microdisk resonators
S. Imamura, R. Watahiki, R. Miura +2
Single-walled carbon nanotubes have advantages as a nanoscale light source compatible with silicon photonics because they show room-temperature luminescence at telecom-wavelengths…
