摘要：
A non-linear semiconductor optical device (3) comprises an active waveguide with a multiple quantum well construction in the active region. The device (3) is supplied with a drive current at the material transparency current with respect to an optical pump. An optical non-linearity appears with respect to input radiation having a wavelength below that of the bandgap equivalent wavelength of the active region (μ
