A fiber Bragg grating (FBG) is a type of distributed Bragg reflector fabricated in a short segment of optical fiber which acts as a filter that reflects particular wavelengths of light and transmits all others. Fiber Bragg grating (FBG) is a type of reflector placed in optical fiber that reflects particular wavelength of light and transmits the required one. FGBs are made by exposing the core of single-mode fiber to a periodic pattern of high ultraviolet light. This produces a permanent increase in refractive index, creating a fixed index modulation according to exposure pattern.
Continuous improvements related to fiber Bragg grating writing system, i.e. flexible automation of fiber and mask handling design, is expected to result in increased demand for fiber Bragg grating, as it is widely used in optical sensing applications. Besides fiber Bragg gratings have several applications in telecommunications and oil & gas industries, application scope is also wide and increasing for smart manufacturing and non-destructive testing, which includes composites, laminates, etc. It is also widely used in pressure, strain, and temperature sensing.
Among the product type segments, uniform fiber Bragg grating type segment in the global fiber Bragg grating market is estimated to register a CAGR of over 14% over the forecast period. This can be attributed to increasing adoption of acrylic fiber Bragg grating due to its strong wavelength reflected as it satisfies the Bragg condition.
On the basis of application segments, optical fiber sensing segment is projected to register highest CAGR of over 15% owing to factors such as fiber Bragg grating sensors’ ability to overcome challenges associated with electrical sensing such as being lightweight, miniaturized, and having low thermal conductivity, etc.

With so much change all the time, how can executives best prepare their businesses to meet the security challenges of the coming years? CSO Australia, in conjunction with Mimecast, explored this question in an interactive Webinar that looks at how the threat landscape has evolved – and what we can expect in 2019 and beyond.
An interview with CSO's David Braue and Ian Yip, Chief Technology Officer, McAffee.
According to new research conducted by the Ponemon Institute, Australia and New Zealand have the highest levels of data breaches out of the nine countries investigated. This was linked to heavy investment in security detection and an under-investment in security and vulnerability response capabilities
