摘要： 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.

摘要： Quasi-phasematching design to provide an approximation to a desired spectral amplitude response A(f) (102) is provided. An initial phase response ? (f) corresponding to A(f) (104) is generated. Preferably, d2 ? (f)/df2 is proportional to A2(f). Alternatively, ? (f) can be a polynomial in f. A function h(x) is computed such that h(x) and H(f) = A(f) exp(i ?(f) are a Fourier transform pair (106). A domain pattern function d(x) is computed by binarizing h(x) (108) (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 ? (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.
