Notes on microscopy, photonics, open science, optics, and the engineering details behind new imaging tools.
Fourier Pixels: A Single Element That Senses and Generates Structured Light
ETH Zurich built a 10-micron plasmonic pixel that controls amplitude, phase, and polarization at once, working both as a light sensor and a light source.

SPAD Arrays: How Single-Photon Detectors Are Reshaping Microscopy and Imaging
Single-photon avalanche diode arrays are moving from confocal add-ons to widefield cameras and consumer sensors, changing how microscopy captures light.

The Revolution in Microscopy: 10 Trends Reshaping How We See the Invisible
A researcher's map of ten converging trends reshaping microscopy — from computational imaging and SPAD detectors to metasurfaces and quantum microscopy.

This new sensor by Eyeo Imaging increases colour sensitivity by 3x
Since 1976, every color camera sensor has discarded 70% of incoming light. Eyeo, an imec spin-off, replaces absorptive filters with nanophotonic waveguides that route photons instead.

BisQue: A Free, Open-Source ML Platform for 5D Microscopy Data
BisQue is a free, browser-based ML platform for storing, annotating, and analysing up to 5D microscopy data. Supports 100+ formats, Python, MATLAB, and ImageJ.

Are Lasers the Future of Indoor Wireless? A Chip-Scale VCSEL Array at 362 Gbps
A 1 mm² chip packed with 25 lasers just hit 362 Gbps using light instead of radio waves — at half the energy cost of Wi-Fi. Here's what it means.

Why NVIDIA Just Bet $4 Billion on Photonics
NVIDIA invested $4B in optical interconnects. Here's the physics behind why copper is failing AI infrastructure — and why photonics is the answer.

Plano-Convex Lens Orientation: How to Minimise Spherical Aberrations
Orienting a plano-convex lens incorrectly introduces spherical aberrations that blur your focus. Here's the rule every optical designer should follow.
Samsung's Pixel-Level Privacy Display: How OLED Angular Control Works
Samsung's Galaxy S26 Ultra uses a redesigned Black Matrix and dual-pixel architecture to restrict light emission angle per pixel — engineering privacy into the hardware itself.

Open Microscopy Resources: The Community-Built Map
The OpenMicroscopy GitHub repo by Hohlbein Lab curates 80+ free tools: hardware designs, control software, analysis pipelines, and open data repositories.
