Resolution in rotation measurements [PDF]
, 2005 The limiting resolution in optical interferometry is set by the number of photons used, with the functional dependence determined by the state of light that is prepared.

Wavelength-limited optical accordion
Optics Express, 2018 We demonstrate a method to create dynamic optical lattices with lattice constant tunable down to the optical wavelength limit. The periodicity of 1D lattice is to be adjusted by rotating the incoming direction of one of the two interfering laser beams with its fiber port. The relative phase between the stationary and rotating lasers are stabilized with

Two-photon absorption and broadband optical limiting with bis-donor stilbenes [PDF]
, 1997 Large two-photon absorptivities are reported for symmetrical bis-donor stilbene derivatives with dialkylamino or diphenylamino groups. These molecules exhibit strong optical limiting of nanosecond pulses over a broad spectral range in the visible ...

Effect of heavy metals (Ni, Cu, Pb) doped ZnO on the nonlinear optical properties
Materials Research Express, 2020 In this paper, the non-linear optical properties of undoped and doped ZnO thin films were investigated. The films were doped with Ni, Pb, and Cu. an increase in the refractive index against wavelength is apparent for all films up to a certain value of ...

Fundamental Limit to Optical Components [PDF]
Frontiers in Optics 2007/Laser Science XXIII/Organic Materials and Devices for Displays and Energy Conversion, 2007 We prove an upper bound to performance for linear optical components, completely independent of detailed design. For one-dimensional dispersive and slow light structures, the bound depends only on length and maximum dielectric constant.

Light dynamics in glass-vanadium dioxide nanocomposite waveguides with thermal nonlinearity [PDF]
, 2009 We address the propagation of laser beams in Si02-VO2 nanocomposite waveguides with thermo-optical nonlinearity. We show that the large modifications of the absorption coefficient as well as notable changes of refractive index of VO2 nanoparticles ...

Broader, flatter optical spectra of passively mode-locked semiconductor lasers for a wavelength-division multiplexing source [PDF]
, 1997 Using the time domain master equation for a complex electric-field pulse envelope, we find analytical results for the optical spectra of passively mode-locked semiconductor lasers. The analysis includes the effect of optical nonlinearity of semiconductor

Inverted optical bistability and optical limiting in coherently driven exciton–polaritons
APL Photonics, 2023 Exciton–polaritons in optical cavities exhibit strong nonlinearities predominantly because of the third-order Kerr-like interactions mediated by the excitonic component.
