31. One-dimensional photonic crystals can be made of layers deposited or stuck together. 32. Photonic crystals can, in principle, find uses wherever light must be manipulated.33. The trip is accomplished by the " etheroneph ", a nuclear photonic rocket. 34. Eventually, Kouji reaches the Photonic Research Institute despite the efforts of Archduke Gorgon. 35. Implementing this with optical components is difficult, and ideally requires advanced photonic materials. 36. It is the method of choice for calculating the band structure of photonic crystals. 37. Photonics21 also provides advice to European member states on strategic investments in photonic technologies. 38. Capture of a 95 GHz RF tone using the photonic time-stretch digitizer. 39. Various technologies are under development including robotic switch-yards and photonic optical switches. 40. The subwavelength periodicity distinguishes photonic metamaterials from photonic band gap or photonic crystal structures.
