Ultra-High Temperature Gratings

Regenerated gratings seeded by type-I gratings are shown to withstand temperatures beyond 1000 ℃. The method of regeneration offers a new approach to increasing temperature resistance of stable fibre Bragg and other gratings. These ultra-high temperature （UHT） gratings extend the applicability of silicate based components to high temperature applications such as monitoring of smelters and vehicle and aircraft engines to high power fibre lasers.

Stable CW Single-Mode Photonic Crystal Fiber DFB Ring Laser

We demonstrate stable single-mode CW operation of a DFB ring laser based on Er3＋ doped photonics crystal fiber （PCF）. The incorporation of a ring cavity allows one single mode to lase and also suppresses the unwanted effect of self-pulsing. Such a narrow linewidth source in PCF has great potential in spectroscopy.

Structure formation dynamics in drawing silica photonic crystal fibres

The special features of photonic crystal fibres（PCFs）are achieved by their air hole structures.PCF structure is determined and formed by its origin preform design and drawing process.Therefore,structure formation dynamics in drawing PCF is important for the fabrication of PCF achieving desirable structure and thus the intended feature.This paper will investigate structure formation dynamics of PCF drawing in relation to key parameters and conditions,such as hole dimension,temperature,pressure,etc.
