A 14nm logic technology using 2 nd-generation FinFET transistors with a novel subfin doping technique, self-aligned double patterning (SADP) for critical patterning layers, and air-gapped interconnects at performance-critical layers is described. The transistors feature rectangular fins with 8nm fin width and 42nm fin height, 4 th generation high-k metal(More)
We use the third-and fourth-order autocorrelation functions g (3) (τ 1 ,τ 2) and g (4) (τ 1 ,τ 2 ,τ 3) to detect the nonclassical character of the light transmitted through a photonic-crystal nanocavity containing a strongly coupled quantum dot probed with a train of coherent light pulses. We contrast the value of g (3) (0,0) with the conventionally used g(More)
The on-chip generation of nonclassical states of light is a key requirement for future optical quantum hardware. In solid-state cavity quantum electrodynamics, such nonclassical light can be generated from self-assembled quantum dots strongly coupled to photonic crystal cavities. Their anharmonic strong light-matter interaction results in large optical(More)
We investigate the influence of exciton-phonon coupling on the dynamics of a strongly coupled quantum dot-photonic crystal cavity system and explore the effects of this interaction on different schemes for nonclassical light generation. By performing time-resolved measurements, we map out the detuning-dependent polariton lifetime and extract the spectrum of(More)
SUMMARY A bi-directional, latching microactuator which combines the use of micromachined permanent magnets and electromagnets has been developed. The device is fabricated primarily from Ni/Fe permalloy using LIGA technology, whereas the permanent magnets are cut from NdFeB using micro-electro discharge machining. The permanent magnets allow the actuator to(More)
Strongly coupled quantum dot-cavity systems provide a non-linear configuration of hybridized light-matter states with promising quantum-optical applications. Here, we investigate the coherent interaction between strong laser pulses and quantum dot-cavity polaritons. Resonant excitation of polaritonic states and their interaction with phonons allow us to(More)
Progress in cavity quantum electrodynamics (cQED) trends to decreasing mode volume and increasing light-matter interaction. We demonstrate a metal-semiconductor nanopillar cQED system that exhibits bright single-photon generation, strong Purcell enhancement, and viability as a new platform for cQED.
We demonstrate a novel method for deterministic charging of InAs quantum dots embedded in photonic crystal nanoresonators using a unique vertical p–n–i–n junction within the photonic crystal membrane. Charging is confirmed by the observation of Zeeman splitting for magnetic fields applied in the Voigt configuration. Spectrally resolved photoluminescence(More)
Product definition technology has evolved in such a way as to encourage the proliferation of data formats used within the product lifecycle for various use cases. One such product development framework being proposed in industry today is the model-based enterprise (MBE), which is operationally driven by the model-based definition (MBD) of products. This(More)
