Department(s)/lab(s): Engineering Science | Dynamic Optics and Photonics Group @ Oxford
Summary:

Booth's Dynamic Optics and Photonics Group develops adaptive-optics methods (deformable mirrors, spatial light modulators) for aberration correction in confocal, two-photon and super-resolution (STORM/STED/SIM) microscopy, enabling higher-fidelity deep-tissue biomedical imaging, alongside applications in ultrafast laser micro-fabrication of photonic devices.

Department(s)/lab(s): Astronomy | Bottom Exoplanet Imaging Lab @ UCB
Summary:

Bottom builds high-contrast coronagraphic instruments and adaptive-optics systems for direct imaging and characterization of exoplanets, including infrared detector and instrument-concept development for the Habitable Worlds Observatory. The group is actively recruiting postdocs interested in astronomical instrumentation.

Department(s)/lab(s): Institute of Applied Optics (ITO) | Herkommer Group - Design and Simulation of Optical Systems (ITO) @ Stuttgart
Summary:

Herkommer holds the chair for Design and Simulation of Optical Systems at Stuttgart's Institute of Applied Optics (ITO), the group behind much of the optical-design side of two-photon-3D-printed micro-optics -- printing complete multi-lens objectives on the tip of a single-mode fibre, which enables ultrathin endoscopic imaging and micro-objectives that cannot be made by conventional polishing. Related work covers freeform and metasurface optics, aberration theory, and adaptive/computational imaging. Long-running collaboration with Giessen (existing PI) at the 4th Institute of Physics. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), a borderline inclusion on the microscopy axis: the group does not do sensing itself, but it makes the optics that get a diffraction-limited spot into places you otherwise cannot reach -- directly useful for fibre-coupled NV probes and endoscopic quantum sensing.

Department(s)/lab(s): School of Physics / Sydney Institute for Astronomy | Sydney Astrophotonic Instrumentation Laboratory (SAIL) @ USyd
Summary:

Leon-Saval co-invented the photonic lantern and is the fibre-device engineer of the SAIL programme. His group designs, draws and characterises multicore fibres, mode-selective lanterns, OH-suppression fibre Bragg gratings and hexabundles, and increasingly applies the same devices outside astronomy — in telecommunications space-division multiplexing and in medical endoscopy and imaging through fibre. The unifying technical problem is coupling a spatially-incoherent, aberrated beam into single-mode circuitry without losing photons. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — photonic lanterns are directly applicable to quantum sensing readout: the same device that feeds a seeing-limited telescope beam into a single-mode spectrograph can feed fluorescence from a scattering biological sample into a single-mode quantum-limited detector, preserving the photon budget that a pT/sqrt(Hz) NV measurement depends on.

Department(s)/lab(s): Physics | Photonics Group (Biophotonics) @ Imperial
Summary:

Paterson develops adaptive-optics and wavefront-sensing techniques to correct optical aberrations in fluorescence microscopy and imaging through complex/turbid media, improving resolution and depth in biological and biomedical imaging.

Department(s)/lab(s): School of Physics / Sydney Institute for Astronomy | Tuthill High Angular Resolution Group @ USyd
Summary:

Tuthill is the world's leading practitioner of aperture-masking interferometry and its modern photonic successors. His group's instruments — GLINT (a photonic nuller that destructively interferes starlight on a chip), Dragonfly, and the kernel-phase analysis framework — exist to recover structure at and below the formal diffraction limit of the telescope, in the photon-starved, speckle-dominated regime where naive imaging fails. Science targets are the dusty pinwheel nebulae of Wolf-Rayet binaries, protoplanetary discs and direct detection of exoplanets. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — this is the astronomy entry in the search that most closely mirrors the intellectual structure of quantum sensing: the instrument's performance is set by a fundamental noise floor (photon and speckle noise, analogous to the shot-noise floor at pT/sqrt(Hz)), and the entire game is designing an estimator and a hardware front end that saturate it. Preferred attribute strongly present.

Department(s)/lab(s): Molecular and Cell Biology | Upadhyayula Lab @ UCB
Summary:

Upadhyayula (trained with Eric Betzig at Janelia) develops multifunctional adaptive-optical super-resolution microscopy and the large-scale computational pipelines needed to reconstruct terabyte- to petabyte-scale 3D subcellular dynamics datasets. The group is actively recruiting postdocs.
