    • Wavelength combining for nonlinear frequency conversion is provided having nonlinear feedback to the sources being combined. Power that is fed back to the sources is obtained from within a wavelength conversion device. Therefore, the feedback power to a source has a nonlinear dependence on input power provided by that source to the wavelength conversion device. Such nonlinear feedback can advantageously reduce the sensitivity of the output power from the wavelength conversion device to variations in the nonlinear coefficients of the conversion device. The reason for this reduced sensitivity is that in preferred embodiments, the feedback power increases if a nonlinear coefficient decreases. This increased feedback tends to increase the power supplied to the conversion device, thus mitigating the effect of the reduced nonlinear coefficient.
    • 提供了用于非线性频率转换的波长组合,其具有对被组合的源的非线性反馈。 从波长转换装置获得反馈到源的功率。 因此,到源的反馈功率对于由该源提供给波长转换器件的输入功率具有非线性依赖性。 这种非线性反馈可以有利地降低来自波长转换装置的输出功率对转换装置的非线性系数变化的灵敏度。 这种灵敏度降低的原因是在优选实施例中,如果非线性系数减小,则反馈功率增加。 这种增加的反馈倾向于增加提供给转换装置的功率,从而减轻减小的非线性系数的影响。

    • Quasi-phasematching design to provide an approximation to a desired spectral amplitude response A(f) is provided. An initial phase response φ(f) corresponding to A(f) is generated. Preferably, d2φ(f)/df2 is proportional to A2(f) . A function h(x) is computed such that h(x) and H(f) = A (f ) exp (iφ (f ) ) are a Fourier transform pair. A domain pattern function d(x) is computed by binarizing h(x) (i.e., approximating h(x) with a constant-amplitude approximation) . In some cases, the response provided by this d(x) is sufficiently close to A(f) that no further design work is necessary. In other cases, the design can be iteratively improved by modifying φ(f) responsive to a difference between the desired response A(f) and the response provided by domain pattern d(x) . Various approaches for binarization are provided. The availability of multiple binarization approaches is helpful for making design trades (e.g., in one example, fidelity to A(f) can be decreased to increase efficiency and to increase domain size) .

    • Quasi-phasematching design to provide an approximation to a desired spectral amplitude response A(f) is provided. An initial phase response φ(f) corresponding to A(f) is generated. Preferably, d 2 φ(f) /df 2 is proportional to A 2 (f). Alternatively, φ(f) can be a polynomial in f.
