Latest Patents

Luo's latest patents include an innovative Erbium-doped fiber amplifier with automatic gain control. This technology involves placing an Erbium doped fiber amplifier (EDFA) in a laser cavity to effectively clamp the gain of the amplifier. The design of the laser cavity is optimized to minimize the effects of relaxation oscillations and spectral hole burning. In a preferred embodiment, the laser cavity supports a lasing wavelength that ensures the saturation energy at the laser wavelength is less than that at the signal wavelengths. The implementation of this technology in an erbium doped fiber setup features a laser wavelength that is shorter than that of the signal wavelengths, maintaining a separation of no more than approximately 75% of the width of the spectral hole. Additionally, the compounding of relaxation oscillations can be significantly reduced by varying the length of the fiber within each laser cavity, thereby altering the photon round-trip time within each cavity.
