High resolution light intensity spectrum analyzer (LISA) based on Brillouin optical filter.
TLDR
A high-resolution light intensity spectrum analyzer technique to derive the RF modulation spectrum of optical signals is presented and experimentally confirmed.Abstract:
A high-resolution light intensity spectrum analyzer technique to derive the RF modulation spectrum of optical signals is presented and experimentally confirmed. It uses the XPM nonlinear effect in a dispersion shifted fiber to obtain the light intensity spectrum, and a Brillouin optical filtering method to implement the high resolution spectrometric analysis. Measured RF spectra of PRBS modulated optical signals at 2.5 Gb/s and 10 Gb/s are presented and compared with their corresponding ones obtained in the electrical detection domain to confirm the capabilities of the method. Influence of fiber electrostriction effect is measured and analyzed.read more

Enhanced directional excitation and emission of single emitters by a nano-optical Yagi-Uda antenna.
TL;DR: 3D numerical calculations demonstrate that the interaction of a single quantum emitter with the electromagnetic field is both enhanced and directed by a nano-optical Yagi-Uda antenna, making such antennas a promising candidate for compact easy-to-address planar sensors.

TL;DR: In this article, the authors measured the optical absorptance of superconducting nanowire single photon detectors and found that 200-nm-pitch, 50-fill-factor devices had an average absorption of 21% for normally-incident front-illumination of 1.55-µm-wavelength light polarized parallel to the nanowires, and only 10% for perpendicularly-polarized light.

Nanofibers drawing and nanodevices assembly in poly(trimethylene terephthalate).
TL;DR: The results suggest that the PTT nanophotonic fibers/wires would be promising candidates in constructing miniaturized photonic devices and ultracompact photonic integrated circuits (PICs), and a one-step drawing as an alternative to the standard optical bench technique.

TL;DR: It is found that, remarkably, absorbed parallel-polarized photons were more likely to result in detection events than perpendicular-polarsized photons, and a hypothesis is presented that qualitatively explains this result.

TL;DR: In this article, the authors demonstrate very high-resolution optical spectrometry based on stimulated Brillouin scattering between a swept-tuned laser and a test optical signal, along with spectral measurements of unmodulated and modulated optical sources showing 0.08-pm resolution and 80dB dynamic range.

TL;DR: It is shown that electrostriction contributes significantly to self-action effects in optical fibers, adding 19% to the nonlinear refractive index for fields that vary slowly compared with the ~1-ns time scale of the acoustic response.

TL;DR: In this article, the optical power spectrum of a signal externally modulated using a Mach-Zehnder modulator is calculated analytically for binary signals for which the drive signal has either raised-cosine or Bessel-filtered pulse shape as well as for duobinary signals created by Bessel filtering.
