Fast control of the transverse structure of a light beam using acousto-optic modulators
Mahdieh Chartab Jabbari, Cheng Li, Xialin Liu +4
Fast, reprogrammable control over the transverse structure of light beams plays an essential role in applications such as structured illumination microscopy, optical trapping, and…
Modeling beam propagation in a moving nonlinear medium
Ryan Hogan, Giulia Marcucci, Akbar Safari +4
Fully describing light propagation in a rotating, anisotropic medium with thermal nonlinearity requires modeling the interplay between nonlinear refraction, birefringence, and the…
Using an acousto-optic modulator as a fast spatial light modulator
Xialin Liu, Boris Braverman, Robert W. Boyd
High-speed spatial light modulators (SLM) are crucial components for free-space communication and structured illumination imaging. Current approaches for dynamical spatial mode gen…
Beam deflection and negative drag in a moving nonlinear medium
Ryan Hogan, Akbar Safari, Giulia Marcucci +2
Light propagating in a moving medium with refractive index other than unity is subject to light drag. While the light drag effect due to the linear refractive index is often neglig…
A classical model of spontaneous parametric down-conversion
Girish Kulkarni, Jeremy Rioux, Boris Braverman +2
We model spontaneous parametric down-conversion (SPDC) as classical difference frequency generation (DFG) of the pump field and a hypothetical stochastic "vacuum" seed field. We an…
Confocal super-resolution microscopy based on a spatial mode sorter
Katherine K. M. Bearne, Yiyu Zhou, Boris Braverman +6
Spatial resolution is one of the most important specifications of an imaging system. Recent results in quantum parameter estimation theory reveal that an arbitrarily small distance…
Multiprobe time reversal for high-fidelity vortex-mode-division multiplexing over a turbulent free-space link
Yiyu Zhou, Jiapeng Zhao, Boris Braverman +5
The orbital angular momentum (OAM) of photons presents a degree of freedom for enhancing the secure key rate of free-space quantum key distribution (QKD) through mode-division mult…
Ultrafast pulse measurement via time-domain single-pixel imaging
Jiapeng Zhao, Jianming Dai, Boris Braverman +2
In contrast with imaging using position-resolving cameras, single-pixel imaging uses a bucket detector along with spatially structured illumination for image recovery. This emergin…
Fast Generation and Detection of Spatial Modes of Light using an Acousto-Optic Modulator
Boris Braverman, Alexander Skerjanc, Nicholas Sullivan +1
Spatial modes of light provide a high-dimensional space that can be used to encode both classical and quantum information. Current approaches for dynamically generating and measuri…
High-fidelity spatial mode transmission through a 1-km-long multimode fiber via vectorial time reversal
Yiyu Zhou, Boris Braverman, Alexander Fyffe +5
The large number of spatial modes supported by standard multimode fibers is a promising platform for boosting the channel capacity of quantum and classical communications by orders…
Robust kHz-linewidth distributed Bragg reflector laser with optoelectronic feedback
Megan Yamoah, Boris Braverman, Edwin Pedrozo-Peñafiel +3
We demonstrate a combination of optical and electronic feedback that significantly narrows the linewidth of distributed Bragg reflector lasers (DBRs). We use optical feedback from…
Preventing and Reversing Vacuum-Induced Optical Losses in High-Finesse Tantalum (V) Oxide Mirror Coatings
Dorian Gangloff, Molu Shi, Tailin Wu +11
We study the vacuum-induced degradation of high-finesse optical cavities with mirror coatings composed of SiO-TaO dielectric stacks, and present methods to protect…
Passive intrinsic-linewidth narrowing of ultraviolet extended-cavity diode laser by weak optical feedback
Polnop Samutpraphoot, Sophie Weber, Qian Lin +7
We present a simple method for narrowing the intrinsic Lorentzian linewidth of a commercial ultraviolet grating extended-cavity diode laser (TOPTICA DL Pro) using weak optical feed…
Spatial and temporal characterization of a Bessel beam produced using a conical mirror
K. B. Kuntz, B. Braverman, S. H. Youn +3
We experimentally analyze a Bessel beam produced with a conical mirror, paying particular attention to its superluminal and diffraction-free properties. We spatially characterized…
