Enhanced Erbium–Zirconia–Yttria–Aluminum Co-Doped Fiber Amplifier
IEEE Photonics Journal, 2015 An efficient optical amplifier is demonstrated using an improved erbium-zirconia-yttria-aluminum co-doped fiber (Zr-EDF) as the gain medium. With a combination of both Zr and Al, we could achieve a high erbium doping concentration with an absorption loss

Ultranarrow-Linewidth Brillouin/Erbium Fiber Laser Based on 45-cm Erbium-Doped Fiber
IEEE Photonics Journal, 2015 We demonstrate an ultranarrow-linewidth Brillouin/erbium fiber laser (BEFL), in which 45-cm commercialized erbium-doped fiber (EDF) acts as both the Brillouin and linear gain media. The Brillouin pump threshold of the BEFL is in submilliwatts. Its 980-nm

Ultrafast optical properties and applications of anisotropic 2D materials. [PDF]
NanophotonicsAbstract Two‐dimensional (2D) layered materials exhibit strong light‐matter interactions, remarkable excitonic effects, and ultrafast optical response, making them promising for high‐speed on‐chip nanophotonics. Recently, significant attention has been directed towards anisotropic 2D materials (A2DMs) with low in‐plane crystal symmetry. These materials
