Abstract

Simultaneous, diffraction-limited control of multiple optical beams is crucial for applications ranging from lithography to optogenetics, deep tissue imaging, and tweezer-based manipulation of cells, particles, or atoms. Despite the desire to address wider fields of view, deeper volumes, and increasingly-disordered media, spatially-varying aberrations currently restrict parallelized steering to a limited "isoplanatic" region over which the point spread function is invariant. Here, we overcome this limitation by combining individual propagation kernels accounting for site-specific aberrations into a single spatial light modulator (SLM) hologram. This "aberration-space holography" unlocks precise, parallel holographic shaping over the SLM's entire Nyquist-limited volume, enabling us to realize full-field, anisoplanatic aberration compensation for the first time. By simultaneously correcting 50 isoplanatic patches with 8 principal aberration modes, we demonstrate a full-field optical tweezer array with 8x larger field of view than the best isoplanatic correction. Extending to 3D, we increase the volume of a multiphoton volumetric display by 12x. These performance enhancements are immediately accessible to a diverse range of applications through our open-source software implementation, which combines aberration-space holography with automated experimental feedback, wavefront calibration, and alignment.

Geometric Phases and Holonomy in Structured Optical Fields

Geometric phases are widely used in modern optics, yet their meaning and underlying geometry depend on the actual physical settings, which can substantially differ from one another. This tutorial article introduces geometric phases in nanophotonic systems, focusing on the interaction of structured light with nanostructures or metaatoms. We compare the present setting with conventional geometric phases of structured-light optics and show that similar phase laws may correspond to genuinely different underlying geometries. Our aim is to provide a pedagogical bridge between the mathematical language of geometric phases and experimentally relevant examples from nanophotonics.

Induced Directional Switching of Platicon Microcombs in Photonic Crystal Ring Resonators

Microcombs in normal-dispersion photonic crystal ring resonators (PhCRs) are versatile building blocks for next-generation integrated photonic circuits, but their inherent backward-propagation bias necessitates optical circulators or complex filtering for comb extraction, creating a significant bottleneck for full on-chip integration and precluding self-injection locking schemes. In this work, we introduce Side-mode Induced Forward Forcing (SIFF), a robust method to control and reverse this directionality. By engineering auxiliary mode splittings on resonances adjacent to the pump, we steer the nonlinear dynamics to favor stable, forward-propagating platicon states. We identify an optimal coupling condition that ensures forward-comb dominance across a wide parameter range. Our findings, validated numerically and experimentally, enable circulator-free, integrated normal-dispersion microcombs compatible with self-injection locking, offering a scalable architecture for compact telecommunications and sensing systems.

Programmable Intrinsic Circularly Polarized Emission

Circularly polarized luminescence (CPL) is central to chiral photonics, yet programming circularly polarized emission at the nanoscale remains challenging. Here, we program intrinsic CPL at its microscopic origin in laser-written all-inorganic perovskite nanocrystals embedded in glass. High-resolution transmission electron microscopy reveals a core-shell-like variation in interplanar spacing associated with intrinsic CPL, consistent with torsional lattice distortion. The torsional lattice distortion breaks inversion symmetry, while density functional theory calculations show that it lifts the spin degeneracy of the band-edge electronic states. Power-dependent measurements further reveal a transition from birefringence-mediated circular polarization to intrinsic CPL, accompanied by the emergence of a distinct core-shell-like lattice distortion in the nanocrystals. By tuning the incident linear polarization angle and focal depth, we deterministically control both the handedness and magnitude of the intrinsic CPL, with |glum| of approximately 4 ^ 10^-3. These results show that programmable intrinsic CPL originates from the structural and electronic properties of the emitting nanocrystals, enabling circularly polarized emission to be controlled at its microscopic origin and spatially encoded within a monolithic material.
