Thulium-Doped Fiber Laser Amplifier at 1762 nm

Introduction The role of a fiber amplifier is to increase the signal from an optical source, such as a laser, and this function is vital for effective telecommunications. In practice, this fiberoptic component is pumped with energy corresponding to a specific wavelength range, and the original optical signal is amplified and propagated onward. This technology typically consists of fiberoptic cable doped with rare earth metals, such as thulium. Unfortunately, with conventional amplifiers, the window of wavelengths that is available for this type of amplification is limited to 1260-1675 nm, and as the demands increase on telecommunications networks, amplifiers outside of this range will help to increase the flexibility and capacity of such systems. Technology Description Professor Blinov at the University of Washington has developed a thulium-doped fiber amplifier (TDFA) that accommodates laser amplification near 1760 nm. This technology demonstrates a greater than 20-dB optical gain with a 1-W output. Business Opportunity The ability to amplify laser light within fiberoptics near 1760 nm presents opportunities in telecommunications. This technology broadens the spectral region that is accessible to applications within this field and promises fiberoptic networks that are more flexible and more powerful. Additional applications include light detection and ranging (LIDAR). Stage of Development A working prototype of this technology is in development. Intellectual Property Position The UW is currently reviewing this technology for worldwide patent protection.
