Abstract Combining external control with long spin lifetime and coherence is a key challenge for solid state spin qubits. Tunnel coupling with electron Fermi reservoir provides robust charge state control in semiconductor quantum dots, but results in

Two-dimensional coherently coupled photonic crystal ion-implanted bottom emitting vertical cavity surface emitting laser arrays are demonstrated. Subthreshold luminescence shows uniform current injection below threshold, benefiting from the improved

Epitaxial lift-off (ELO) is a process technology that can enable substantial performance enhancement and cost reduction for epitaxially grown III–V devices. [1]–[4] In particular, GaAs-based inverted metamorphic multijunction (IMM) solar cells ar

We demonstrate 2-dimentional coherently coupled bottom-emitting VCSEL arrays. In-phase operation has been obtained from 3-element triangular arrays, while out-of-phase operation has been obtained from 2x2, 3x3, and 4x4 arrays.
