“…Semiconductor quantum dots (QDs) have been widely used for various ultrafast optoelectronic devices such as single electron transistors, bistable elements, modulators, and lasers [117][118][119][120][121][122]. Several studies on quantum dot (QD) systems were carried out in the last decade, mainly on Cd chalcogenides [123].…”

“…However, they have low damage threshold and cannot sustain strong laser pumping for a long time. Quantum dots (QDs) have been reported to have emission cross sections as high as 7 × 10 −15 cm 2 [166] (at the level of the best performing dye molecules). However, the reported experimental values of the optical gain in the QD based amplifying media do not exceed 1000 cm −1 [167].…”

Optical metamaterials have redefined how we understand light in notable ways: from strong response to optical magnetic fields, negative refraction, fast and slow light propagation in zero index and trapping structures, to flat, thin and perfect lenses. Many rules of thumb regarding optics, such as mu = 1, now have an exception, and basic formulas, such as the Fresnel equations, have been expanded. The field of metamaterials has developed strongly over the past two decades. Leveraging structured materials systems to generate tailored response to a stimulus, it has grown to encompass research in optics, electromagnetics, acoustics and, increasingly, novel hybrid materials responses. This roadmap is an effort to present emerging fronts in areas of optical metamaterials that could contribute and apply to other research communities. By anchoring each contribution in current work and prospectively discussing future potential and directions, the authors are translating the work of the field in selected areas to a wider community and offering an incentive for outside researchers to engage our community where solid links do not already exist.

“…Recently, InAs/In x Ga 1Àx As quantum dots-in-a-well (DWELL) structures have attracted much attention due to their advantages for photoelectric applications [1,2]. A lot of studies have been done on the properties of DWELL structure in which quantum dots (QDs) are surrounded by a quantum well [3][4][5][6].…”
