Summary: This article introduces a solution for enabling vertical parallax in solid-state leaky mode devices by integrating an electrooptic phased array. It presents a simple proof of concept for an acousto-optic/electro-optic modulator deflecting in two axes and describes how this concept could be further developed and adapted for transparent large-format and near-eye holographic displays.

Summary: We developed a tunable system for shaping the spectral and spatial frequency of ultrashort laser pulses using acousto-optic filters. This system allows for the creation of arbitrary axially symmetric multi-wavelength field configurations and enables high-speed control. Experimental results demonstrate the independent generation of different colored intensity distributions from a single laser beam using this system.

Summary: A novel optical beam deflector based on a Lithium niobate waveguide was demonstrated, operating in both electro-optic and thermo-optic modes. In the electro-optic mode, serrated electrodes induced a non-uniform refractive index change via the Pockels effect, resulting in linearly changing deflected distance with applied voltage. The deflection speed reached up to 2.5 GHz experimentally. The deflector also operated in the thermo-optic mode, where deflection distance depended on applied electric power and varied quadratically with applied voltage. The distinct operating modes enable the LN optical beam deflector to be qualified for various tasks.

Summary: An ultra-widely tunable acousto-optic add-drop filter based on acoustically-induced polarization conversion of cladding-etched single-mode fiber is proposed and demonstrated. It covers a wavelength range from 1081 nm to 1582 nm with a tuning band larger than 500 nm. The filter has reconfigurable band-pass and band-rejection filtering characteristics, and offers advantages such as ultra-wide wavelength tuning range, fast tuning speed, simple fabrication, and zero frequency shift. It has potential applications in WDM communication, ultra-wide tunable lasers, signal processing, swept-source optical coherence tomography (SS-OCT), and wideband spectroscopy.

Summary: This study reports a novel optical scheme of an annular optical trap based on an acousto-optic tunable spatial filter. The design of the optical trap was proposed and validated, with experimental demonstrations showing controllable arrangements of floating particles into circular patterns, aggregation, and disaggregation. The dynamical adjustment of the trapping field potential diameter was achieved through programmable frequency-swept controlling of the acousto-optic filter.

Summary: Due to superior imaging resolution and range, LiDAR is becoming an essential optical perception technology for intelligent automation systems. However, many existing beam-steering technologies are still bulky, fragile, and expensive. This study presents an on-chip acousto-optic beam-steering technique that overcomes these challenges. By utilizing Brillouin scattering, this technique achieves frequency-angular resolving LiDAR with a simple device construction, control system, and detection scheme, demonstrating a wide field of view and high angular resolution.

Summary: Optical isolators are essential for protecting lasers from unwanted reflections and maintaining phase-stable coherent operation in optical systems. Integrated chip-scale optical systems require fully integrated optical isolators, but existing approaches face challenges in material integration. In this study, a non-reciprocal electro-optic isolator on thin-film lithium niobate is achieved, with high performance in terms of isolation and insertion loss. This represents an important advancement towards practical on-chip optical isolators.

Summary: This research demonstrates a highly linear lithium niobate (LN) modulator with an ultra-high spurious-free dynamic range (SFDR) using a ring-assisted Mach-Zehnder interferometer configuration. The modulation does not require active feedback controls to suppress third-order intermodulation distortions (IMD3), resulting in a significant improvement over previous results in the thin-film LN platform.
