Patent number: 12085836Abstract: An optical amplifier of the present disclosure includes a Raman amplification unit and a parametric amplification unit that is configured of a second-order nonlinear element including a PPLN waveguide. In the optical amplifier, second harmonic lights are generated from a fundamental wave light having a wavelength that is slightly detuned to a shorter wavelength side with respect to a phase matching wavelength of the second-order nonlinear element, and is utilized as excitation light for the parametric amplification unit. By utilizing the excitation light based on the fundamental wave light of the wavelength detuned from the phase matching wavelength, a phase matching curve can be obtained in a wide band in a difference frequency generation (DFG) process of the second-order nonlinear element. The reduction in conversion efficiency of the wavelength near the excitation light in the parametric amplification unit is compensated by the Raman amplification unit.Type: GrantFiled: July 29, 2020Date of Patent: September 10, 2024Assignee: Nippon Telegraph and Telephone CorporationInventors: Takushi Kazama, Takeshi Umeki, Takahiro Kashiwazaki, Osamu Tadanaga, Koji Embutsu, Nobutatsu Koshobu, Asuka Inoue, Ryoichi Kasahara
