This paper reports precision measurements of the electromagnetic permittivity of five highly refractive, single-crystal materials, SrTiO3, KTaO3, rutile TiO2, LiTaO3, and LiNbO3, using a single, well-controlled, frequency-scalable procedure over the

We introduce a technique to manipulate an optical frequency comb on a line-by-line basis using stimulated Brillouin scattering (SBS). The narrow-linewidth SBS process has been used to address individual lines in optical frequency combs, but previous

This paper presents an optical sampler based on the combination of a mode-locked laser and external acousto-optic delay modulator, and demonstrates its use in a non-uniformly subsampled photonic link. Delay modulation of the laser's uniformly spaced

This paper demonstrates a non-uniform optical sampler based on the combination of a pulsed laser and an acousto-optic delay modulator. By using this to non-uniformly sub-sample a photonic link, signal frequencies well above the Nyquist frequency can

This paper demonstrates an acousto-optic technique for delay modulation of wide bandwidth RF photonic signals. By modulating RF delay, sideband power is varied 20 dB/frequency decade over the 0.1–10 GHz range, potentially enabling for applications

We introduce a method whereby the electromagnetic field that governs the force on a Rayleigh particle can be tailored such that the resultant force field conforms to a desired geometry. The electromagnetic field is expanded as a set of vector spheric

This paper presents a detailed investigation of the motion of individual micro-particles in a moderately-viscous liquid in direct response to a local, laser-induced temperature gradient. By measuring particle trajectories in 3D, and comparing them to

We report on the application of an optical beam to redirect sheathed micro-fluidic flow without direct interaction with the sample. The hydrodynamic properties of the sheath are locally modified resulting in a sample location shift.

These results demonstrate the ability of a commercial LiNbO3 EO modulator to withstand damage from direct pulsed RF input up to 200 W. However, short-term disruption occurred at a few Watts, which suggests a need for improved modulator thermal design
