 Nikos Bamiedakis: 'Polymer Spiral Waveguide' |
| Nikos Bamiedakis 'Polymer Spiral Waveguide' The photo was taken when He-Ne light was coupled into a polymer spiral waveguide. Optical fibres were used at both ends. The shape of the waveguide can be easily seen as well as the scattered light at the input/output due to coupling losses and at the middle of the spiral due to bending losses (acute s-bend). |
