WebMar 12, 2024 · The nanobeam cavity with a small mode volume enhances light emission from a chirality-identified single CNT. The cavity-coupled light propagates into the waveguide and is emitted from the waveguide facet with a sharp linewidth and a large off-resonance rejection. Our CNT PL device schematic is illustrated in Fig. 1 (a).

WebA photonic crystal coupled-cavity waveguide created on silicon-on-insulator is designed to act as a refractive-index-sensing device at midinfrared wavelengths around 4 μm. To … WebThe PhC cavity acts as a tunable narrowband reflector giving wavelength selectivity. The FM was achieved by thermo-optical modulation of the reflector via a p-n junction. Single-mode operation was ensured by the short cavity length, overlapping only one longitudinal laser mode with the reflector. synonyms for the word know
