Emerging Device Applications From Strong Light–Matter Interactions in 2D Materials

Advanced Science, Volume 13, Issue 17, 23 March 2026.
Two‐dimensional semiconductors enable extremely compact optoelectronic devices such as solar cells, sensors, LEDs, and lasers. Their strong light–matter interactions allow efficient light emission, detection, and energy conversion. This review article discusses the recent progress in integrating these materials with optical cavities and nanostructures ...

Self-mixing interference effects in tunable diode laser absorption spectroscopy [PDF]

, 2009
We report the effects of self-mixing interference on gas detection using tunable diode laser spectroscopy. For very weak feedback, the laser diode output intensity gains a sinusoidal modulation analogous to that caused by low finesse etalons in the ...

Deep‐UV Photonic Crystal Surface‐Emitting Lasers

Laser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.
The first deep‐UV photonic crystal surface‐emitting lasers (PCSELs) at 279 nm are demonstrated under pulsed optical pumping. The PCSELs have single‐mode emission with a 17‐pm linewidth and a divergence angle of less than 1∘$^{\circ }$. Experimental results highlight the impact of the filling factor choice on the lasing mode and the far‐field emission ...
