The possibility for increasing the efficiency of photovoltaic solar cells via sequential
absorption of photons in a single material has a relatively long history. Starting with the …

Photonic integrated circuits (PICs) have enabled numerous high performance, energy
efficient, and compact technologies for optical communications, sensing, and metrology …

The strong-coupling regime of cavity quantum electrodynamics (QED) represents the light–
matter interaction at the fully quantum level. Adding a single photon shifts the resonance …

The fine structure of excitons is studied by magnetophotoluminescence spectroscopy of
single self-assembled In (Ga) As/(Al) GaAs quantum dots. Both strength and orientation of …

We demonstrate coupling and entangling of quantum states in a pair of vertically aligned,
self-assembled quantum dots by studying the emission of an interacting electron-hole pair …

Quantum dots are typically formed from large groupings of atoms and thus may be expected
to have appreciable many-body behavior under intense optical excitation. Nonetheless, they …

We have investigated GaAs-based pin quantum dot solar cells (QDSCs) with 10 up to 20
stacked layers of self-assembled InAs quantum dots (QDs) grown by atomic hydrogen …

Self-assembled strained semiconductor nanostructures have been grown on GaAs
substrates to fabricate quantum dot infrared photodetectors. State-filling photoluminescence …

InAs was grown by molecular-beam epitaxy onto GaAs (001) until quantum dots (QDs)
formed. At this point, the growth was interrupted and the uncovered QDs were investigated …

Most self-assembled quantum dot molecules are intrinsically asymmetric with inequivalent
dots resulting from imperfect control of crystal growth. The authors have grown vertically …
