Light Phase Detection with On-Chip Petahertz Electronic Networks
Ultrafast light-matter interactions lead to optical-field-driven
photocurrents with an attosecond-level temporal response. These photocurrents
can be used to detect the carrier-envelope-phase (CEP) of short optical pulses,
and could be utilized to create optical-frequency, petahertz (PHz) electronics
for information processing. Despite recent reports on optical-field-driven
photocurrents in various nanoscale solid-state materials, little has been done
in examining the large-scale integration of these devices. In this work, we
demonstrate enhanced, on-chip CEP detection via optical-field-driven
photocurrent in a monolithic array of electrically-connected plasmonic bow-tie
nanoantennas that are contained within an area of hundreds of square microns.
The technique is scalable and could potentially be used for shot-to-shot CEP
tagging applications requiring orders of magnitude less pulse energy compared
to alternative ionization-based techniques. Our results open new avenues for
compact time-domain, on-chip CEP detection, and inform the development of
integrated circuits for PHz electronics as well as integrated platforms for
attosecond and strong-field science
Spectrally reconfigurable quantum emitters enabled by optimized fast modulation
The ability to shape photon emission facilitates strong photon-mediated
interactions between disparate physical systems, thereby enabling applications
in quantum information processing, simulation and communication. Spectral
control in solid state platforms such as color centers, rare earth ions, and
quantum dots is particularly attractive for realizing such applications
on-chip. Here we propose the use of frequency-modulated optical transitions for
spectral engineering of single photon emission. Using a scattering-matrix
formalism, we find that a two-level system, when modulated faster than its
optical lifetime, can be treated as a single-photon source with a widely
reconfigurable photon spectrum that is amenable to standard numerical
optimization techniques. To enable the experimental demonstration of this
spectral control scheme, we investigate the Stark tuning properties of the
silicon vacancy in silicon carbide, a color center with promise for optical
quantum information processing technologies. We find that the silicon vacancy
possesses excellent spectral stability and tuning characteristics, allowing us
to probe its fast modulation regime, observe the theoretically-predicted
two-photon correlations, and demonstrate spectral engineering. Our results
suggest that frequency modulation is a powerful technique for the generation of
new light states with unprecedented control over the spectral and temporal
properties of single photons.Comment: 9 pages, 6 figures; Supplementary Informatio
