Researchers demonstrate an electrically driven nanoscale transmitter based on the broadband quantum shot noise of electrons tunnelling across a feed gap.
Using squeezed states of light combined with a real-time Bayesian adaptive estimation algorithm, deterministic phase estimation with a precision beyond the quantum shot noise limit is demonstrated without any prior knowledge of the phase's value.
Cells are transformed into self-contained, individual lasers with customizable emission properties via the injection of suitable fluorescent dyes and lipids or beads.
Scientists have realized a graphene electro-optic modulator operating with a 30 GHz bandwidth and with a state-of-the-art modulation efficiency of 1.5 dB V−1, paving the way for fast digital communications.
Femtosecond stimulated Raman experiments on the antiferromagnetic system KNiF3 are implemented to understand how the exchange interaction — a crucial interaction that rules magnetic phenomena — is influenced by ultrafast optical excitation.
The room-temperature lasing of a single nanowire containing 50 quantum dots is demonstrated, paving the way towards ultrasmall lasers with extremely low power consumption for integrated photonic systems.
A silicon detector that is capable of long-wavelength photodetection at multi-gigabit per second data rates could prove useful for unlocking a new wavelength window for optical communications.
Researchers have synchronized XUV and VUV attosecond pulses simultaneously generated by high-harmonic generation. Such pulses with different photon energies may be useful for pump–probe experiments.
Researchers show that optical isolators based on nonlinearity cannot provide complete isolation for arbitrary backwards propagating noise, revealing limitations for their practical application.
Researchers used an inverse design algorithm and experimentally demonstrated an integrated polarization beamsplitter with a footprint of 2.4 × 2.4 μm2.
