چکیده

The development of photonic integrated circuits lattice matched to GaAs are desirable for the manufacture of high-power, high-efficiency optical components. In this letter we investigate and describe a process technique based on quantum-well intermixing to achieve multiple band edges in the Al-free 980 nm InGaAs/ InGaAsP/InGaP material system. © 2005 American Institute of Physics. fDOI: 10.1063/1.1946903g

Luminescent characteristics of InGaAsP/InP multiple quantum well structures by impurity-free vacancy disordering

InGaAsP/InP multiple quantum wells with quantum well intermixing (QWI) have been prepared by Impurity-Free Vacancy Disordering (IFVD). The luminescent characteristics were investigated using photoluminescence (PL) and photoreflectance (PR), from which the band gap blueshift was observed. Si3N4, SiO2 and SOG (spin on glass) were used for the dielectric layer to enhance intermixing from the outdi...

Intermixing of InP-based multiple quantum wells for integrated optoelectronic devices

The intermixing characteristics of three widely used combinations of InP based quantum wells (QW) are investigated using the impurity-free vacancy disordering (IFVD) technique. We demonstrate that the bandgap energy shift is highly dependent on the concentration gradient of the as-grown wells and barriers, as well as the thickness of the well, with thinner wells more susceptible to interdiffusi...

طراحی و شبیه‌سازی سلول خورشیدی سه‌پیوندی بر مبنای چاه کوانتومی

In this paper, the purpose is to improve the efficiency of triple-junction solar cell by introducing quantum well into GaAs junction. Firstly, InGaP/GaAs/InGaAs triple-junctions solar cell has been simulated. Then, a multiple stepped quantum wells (MSQWs), in which InGaAs well is sandwiched by InGaAsP as stepped layer, and the barrier is GaAs, has been introduced into intrinsic region of single...

Energy Levels of InGaAs/GaAs Quantum Dot Lasers with Different Sizes

In this paper, we have studied the strain, band-edge, and energy levels of cubic InGaAs quantum dots (QDs) surrounded by GaAs. It is shown that overall strain value is larger in InGaAs-GaAs interfaces, as well as in smaller QDs. Also, it is proved that conduction and valence band-edges and electron-hole levels are size dependent; larger QD sizes appeared to result in the lower recombination...

InGaAsP photonic band gap crystal membrane microresonators*

We have microfabricated two-dimensional ~2D! photonic band gap structures in a thin slab of dielectric material to define reflectors and high-Q microresonators. By selectively omitting holes from the 2D photonic crystal, optical microcavities, and in-plane microresonator switches can be defined. We have designed this structure with a finite difference time domain approach, and demonstrate the e...
