Journal ArticleDOI
Tunable all-optical delays via Brillouin slow light in an optical fiber.
Yoshitomo Okawachi,Matthew S. Bigelow,Jay E. Sharping,Zhaoming Zhu,Aaron Schweinsberg,Daniel J. Gauthier,Robert W. Boyd,Alexander L. Gaeta +7 more
TL;DR: It is demonstrated that stimulated Brillouin scattering can be used to generate all-optical slow-light pulse delays of greater than a pulse length for pulses as short as 16 ns in a single-mode fiber, and strongly suggest that analogous delays can be achieved using stimulated Raman scattering at telecommunication data rates.
Journal ArticleDOI
"Two-Photon" coincidence imaging with a classical source
TL;DR: It is found that any kind of coincidence imaging technique which uses a "bucket" detector in the test arm is incapable of imaging phase-only objects, whether a classical or quantum source is employed.
Journal ArticleDOI
Large optical nonlinearity of indium tin oxide in its epsilon-near-zero region
TL;DR: It is reported that indium tin oxide can acquire an ultrafast and large intensity-dependent refractive index in the region of the spectrum where the real part of its permittivity vanishes, and offers the possibility of designing material structures with large ultrafast nonlinearity for applications in nanophotonics.
Journal ArticleDOI
Superluminal and Slow Light Propagation in a Room-Temperature Solid
TL;DR: It is observed that ions in mirror sites are inversely saturable and cause superluminal light propagation, whereas ions in inversion sites experience conventional saturable absorption and produce slow light.
Journal ArticleDOI
Generating optical orbital angular momentum at visible wavelengths using a plasmonic metasurface
Ebrahim Karimi,Sebastian A. Schulz,Israel De Leon,Hammam Qassim,Jeremy Upham,Robert W. Boyd,Robert W. Boyd +6 more
TL;DR: Karimi et al. as mentioned in this paper showed that a plasmonic metasurface comprising an array of nano-antennas can couple spin-to-orbital angular momentum at thickness much smaller than the wavelength of the light with an efficiency of around 3%.
