11. In 2002, a company called FiberSpace acquired Tunable Photonics. 12. In 2003, SpectraSensors reacquired the remaining intellectual property from Tunable Photonics. 13. This is implemented using a radio receiver having a tunable receiving frequency. 14. A tunable line emission could be useful for image manipulation. 15. Nanowires of potassium niobate have been used to produce tunable coherent light. 16. These 1D PM nanotubes also offer tunable magnetic properties for controlled manipulation. 17. The tunable bridge allows the length of individual strings to be changed. 18. Titanium-doped sapphire ( tunable infrared laser, commonly used for spectroscopy. 19. The wide bandwidth makes them particularly suitable for tunable lasers and pulsed lasers. 20. Other applications include tunable light sources, image recognition systems and adaptive optics.
