A direct UV writing technique that can create multiple Bragg gratings and waveguides in a planar silica-on-silicon chip is enabling sensing applications ranging from individual disposable sensors for ...

Figure 1 Schematic diagram of a three-dimensional integrated multichannel waveguide grating filter: (a) 1:1 planar beam splitter, (b) 1:1 three-dimensional beam splitter, (c) waveguide gratings ...

Raman Scattering in fiber is a nonlinear process that converts some of the photons at fiber laser wavelength to photons at relatively longer wavelength. The higher the laser power the stronger the ...

Stratophase, a spin-off from Southampton University in the UK, has developed a technique to simultaneously write a waveguide and a planar Bragg grating into an optical silicon chip. The technology has ...
