Multiwavelength Hybrid Fiber Raman/Parametric Linear Oscillator
IEEE Photonics Journal, 2015 We demonstrate a linear cavity wideband multiwavelength fiber-based optical parametric oscillator consisting of four fiber Bragg gratings (FBGs). The FBGs center wavelengths are chosen such that they are 3.2 THz (26 nm) and 14.3 THz (115 nm) away from ...

Advanced Materials, EarlyView.The graphic illustrates the design of a hybrid bilayer composed of a liquid crystal hydrogel (LCH) and a liquid crystal network (LCN). The figure highlights the magnetic alignment of the chromonic hydrogel and the thermal‐responsive actuation of the LCN along with the LCH when both layers are aligned or misaligned, enabling programmable, light‐driven ...
