Two subdiffraction focusing mirrors based on the QWP metasurfaces were demonstrated over a broad bandwidth of 210 nm, which converted circularly polarized incident waves into radially polarized and azimuthally polarized waves and focused them into longitudinally polarized spots with FWHMs of 0.38λ‒...
Tailored light potentials for cold atom experiments were realised using a DMD in direct imaging10,11, where the efficiency of the light potential is directly proportional to the number of mirrors in the ‘on’ position and is limited by the diffraction efficiency of the device (typically 30–88...

Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors. Lasers add a mechanism for optical feedback, such as mirrors, that stimulates further emission and generates...
The investigated sample consists of a single layer of low density In(Ga)As QDs grown via molecular beam epitaxy and located at the center of a λ-thick GaAs cavity surrounded by two Al0.9Ga0.1As/GaAs Bragg mirrors with 18(26) pairs. The density of self-assembled InAs quantum dots varies...
However, they require elaborate optical paths and/or dedicated electronic hardware and software which makes the systems complex and expensive. The ones utilizing phase conjugate mirrors show also wavelength dependency. Once established, our setup is easy to adjust, can tolerate misalignments and is ...
