One of his key inventions is the multi-wavelength Raman laser. This advanced laser comprises a Raman fiber forming part of an optical ring, with most components made from optical fiber. The ring features a periodic filter that selectively transmits optical power at multiple equally spaced wavelengths corresponding to the laser output. Radiation at the signal wavelengths propagates in one direction on the ring and is tapped onto an output fiber. An optical isolator is integrated into the ring or the fiber tapped into the ring to suppress radiation traveling in the reverse direction. Additionally, a frequency shifter may be included in the loop to prevent power from concentrating in a single mode, allowing for wide band lasing. A band pass filter can also be inserted into the loop to restrict the lasing band. This invention has been recognized for its potential applications in various fields.
