Competitive Bidirectional Response in Bi‐Polymeric Mechanochromic Cantilevers Toward Color Imaging‐Based VOC Discrimination

Advanced Optical Materials, EarlyView.
In bi‐polymeric mechanochromic cantilevers composed of polydimethylsiloxane (PDMS) and off‐stoichiometry thiol‐ene‐epoxy (OSTE+), differential swelling between the two polymers in response to VOC exposure induces a competitive bidirectional bending and corresponding color changes, with three characteristic response modes related to the Hansen ...

Deep Seek to the Excited States: A Thermally‐Activated Jahn–Teller Effect Achieves Superior Sensitivity for Thermometry at Cryogenic Temperature

Advanced Optical Materials, EarlyView.
A Sb3+‐activated bismuth‐based halide single crystal shifts the onset temperature by ≈200 K. The confluence of the spin‐orbit interaction and the dynamic Jahn–Teller effect is responsible for maximizing the opposite emission changes at different temperatures. A high relative sensitivity (Sr) value of 18.9 % K−1 is obtained at 77 K.

Spectral Peaked Optical Frequency Comb for Highly Sensitive Spectroscopy

Advanced Photonics Research, EarlyView.
Optical frequency combs represent a breakthrough in metrology, and comb mode selection and power scaling are important issues for highly sensitive spectroscopy. This article reviews the development of a spectrally peaked optical frequency comb using the novel phenomenon of spectral peaking for highly sensitive spectroscopy.

Multimodal Luminescence from LaAlO3:Eu3+ via Trap Modulation for High‐Temperature Applications

Advanced Photonics Research, EarlyView.
LaAlO3:Eu3+ (LAO:E) phosphor exhibiting multimode luminescence enabled by multilevel traps spanning shallow to deep states is reported. These traps ensure controlled charge storage and release at room and elevated temperatures. Experimental studies and theoretical calculations reveal the trapping–detrapping mechanism, highlighting LAO:E as a promising ...

Numerical and Experimental Methods for Estimating the Propagation Loss in Microphotonic Waveguides

Advanced Photonics Research, EarlyView.
Finite‐element finite‐difference time domain, eigenmode‐expansion, and volume‐current simulations are benchmarked against cut‐back, ring‐resonator, and OFDR measurements to quantify waveguide propagation loss in integrated photonic circuits. Scattering, absorption, leakage, and back‐reflection contributions are dissected; error sources are ranked; and ...

Techniques and Advances in Ultrafast Photography

Advanced Photonics Research, EarlyView.
This review maps the fast‐growing field of ultrafast photography from early mechanical cameras to modern optical‐computational methods. It organizes techniques into four families (multishot passive/active; single‐shot passive/active), explains how they reach trillion‐frame‐per‐second speeds, compares capabilities and tradeoffs, and highlights ...
