Webb21 okt. 2016 · Quantum photonic integrated circuits (QPICs) on a GaAs platform allow the generation, manipulation, routing, and detection of non-classical states of light, which could pave the way for quantum information processing based on photons. In this article, the prototype of a multi-functional QPIC is presented together with our recent achievements … Webb8 apr. 2024 · This theoretical study addressed the first-order linear and third-order nonlinear optical features of GaAs/GaAsSb/GaAs V-shaped valence band quantum wells. The iterative solutions of the density matrix approach in the framework of a two-level system were used to investigate the changes in the optical absorption coefficients and …

Find the wavelength of radiation whose photons have energy

Webb28 juli 2024 · The GaAs substrate is transparent to a wavelength of 940 nm, thereby reducing the rate of defect reactions due to recombination enhancement, such as diffusion, dissociation, and annihilation. So the InGaAs strain quantum well has better reliability for epitaxial gallium arsenide laser. Webb7 apr. 2024 · The polar plot at the wavelength of 998 nm for the far-filed emission of the coated QDs is also recorded by rotating the polarizer placed before the spectrometer, as shown in Figure 5c. The PL intensity changes slightly with different polarization angles, and forms an approximate ellipse with little ellipticity as the polarizer rotates around. hendrick emergency room buffalo gap rd
