Laser &Photonics Reviews, EarlyView.Ultra‐thin, tunable bandpass filters are a pathway to realizing mid‐infrared spectrometers that are compact, low power, and performant. The authors elicit 141 nanometres of passband tunability in the mid‐infrared in silicon on sapphire zero‐contrast gratings by exploiting silicon's high thermo‐optic coefficient.

Laser &Photonics Reviews, EarlyView.High‐sensitivity, high‐resolution stimulated Raman photoacoustic spectroscopy is achieved by coupling continuous‐wave pump and Stokes beams to a high‐finesse optical cavity. This approach successfully resolves the narrow Raman rotational transition S0(0) of H2 with sub‐kHz spectral resolution and attains an unprecedented sensitivity of 0.5 ppm using ...

Boron Difluoride Formazanate Dye With Donor Planarization Engineering for 1060 nm Laser Activated Photothermal Theranostics. [PDF]
Adv Sci (Weinh)The donor engineering strategy enhances the planarity of the π‐conjugated molecular framework, thereby promoting stronger intramolecular charge transfer (ICT). This structural refinement in FBDFDPA leads to a pronounced bathochromic shift in absorption from the NIR‐I to the NIR‐II region, enabling effective photothermal therapy (PTT) for tumors within ...
