94. Sensing with Undetected Light Using a Nonlinear Thin-Film Metasurface

Invited talk

Nonlinear interferometry allows amplitude and phase information to be transferred between light that senses an object and light that is only detected. The technique exploits correlated photon beams generated via difference frequency generation or parametric fluorescence. When implemented non-degenerately, information can be passed between wavelengths to circumvent the technical and fundamental...

Polarimetric thermal imaging provides information beyond conventional infrared intensity imaging, including surface orientation, material properties and polarisation signatures. Existing mid-wave infrared (MWIR) polarimetric imaging systems typically rely on rotating polarisers, beam splitters or detector-integrated micropolariser arrays, increasing system complexity and limiting compact...

49. Active Dual-directional Spectral Alignment in Silicon Arrayed Waveguide Gratings

Contributed Oral

Fabrication-induced wavelength shifts remain a major limitation in silicon photonic wavelength multiplexers, leading to channel misalignment and degraded spectral performance in dense wavelength-division multiplexing systems [2,3]. Here, we demonstrate a fully packaged silicon photonic chip fabricated on the imec iSiPP50G platform, integrating a 12-channel, 50 GHz bidirectional arrayed...

343. Switchable phase imaging with a free-form non-local metasurface

Conventional imaging systems measure the intensity or amplitude of the optical field. Transparent samples, such as biological cells, are weakly absorbing and exhibit poor contrast in such systems. However, spatial changes in the refractive index and thickness within these samples lead to changes in the phase. Converting these phase variations into amplitude modulations provides a means to...

413. Hyperentangled photon-pair generation from a nonlinear metasurface

Tongmiao Fan (Australian National University)

ANZOS | Photonics and Optics (ANZCOP)

Contributed Oral

Hyperentangled photon pairs are key resources for quantum high-dimensional communications, information processing, imaging, and fundamental studies of nonclassical phenomena. Polarization, orbital angular momentum (OAM), and frequency offer complementary resources for multidimensional quantum photonics [1]. However, conventional generation of such states relies on bulk nonlinear crystals...
