Schematic of the experimental detection device.
How can light help detect harmful gases?
Researchers developed an optical fiber sensor with cobalt‑ and titanium‑doped graphene to better detect ammonia. This work, published in #SPIE_JOM, could support safer environmental and industrial monitoring. https://bit.ly/3OiAtnE
Can stable #lasers work without bulky isolators? 🔦 Researchers show an isolator‑free, temperature‑tuned III‑V laser integrated on a chip.
The design stays stable under optical feedback, enabling simpler, more compact photonic systems for comms & sensing.

How can lasers sculpt tiny optics inside glass? Selective laser etching precisely carves 3D micro‑optics within a single piece of glass. The result: high‑accuracy features that enable compact systems for sensing, imaging, & photonics. Read the #SPIE_JOM article: https://bit.ly/46JwlDo
Image showing two parts labeled (a) and (b). Part (a) displays a color diagram with overlapping red, green, and blue circles, forming secondary colors where they intersect. Part (b) shows three grayscale oval shapes representing light wavelengths of 520 nm, 560 nm, and 600 nm, each with varying intensities of white to gray shading.
Hyperspectral imaging = seeing colors beyond human vision 🌈🔬
Scientists built a smart holographic lens that works with phone-style sensors to capture light data fast. A big leap in detecting disease, pollution & crop health using light alone!
