Large mode area fibers with asymmetric bend compensation
Optics Express, 2011 Fibers with asymmetrical bend compensation offer to completely remove the tradeoff between mode area and single-modedness, with potentially huge impact on high-power amplification. These fibers would be difficult to fabricate, but are the only fundamental-mode strategy that can remove the bend-distortion limitations on mode-area scaling.

Passive Mode-Locked Operation of Large Mode Area Fibre Lasers [PDF]
CLEO/Europe Conference on Lasers and Electro-Optics, 1998 Recently much work on fibre lasers has concentrated on improving the maximum output energy and peak powers available from such systems. An important recent advance in this area has been the development of single transverse-mode, large mode area (LMA-) doped fibre1.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
