    Abstract: In a nest MZI modulator in which each arm includes a child MZI, the power consumption is reduced. The hybrid integrated-type nest MZI modulator of the embodiment 1a is configured so that, instead of placing a relative phase adjusting section in a parent MZI, a bias electrode Bias 90° in which an electric field is applied in the same direction to the polarization direction in both of the upper and lower arms is placed in each child MZI (see FIG. 4B). The bias electrode Bias 90° provided in each child MZI constitute the entirety of a relative phase adjusting section. The optical signals are subjected to a phase change after the output from the child MZI (see FIG. 1A), because such relative phase adjusting section can subject the optical signals of the upper and lower arms of the child MZI to a shift change in the same direction, respectively.

    Abstract: An interferometer used for modulating an optical signal with an electrical signal is described, where the optical signal can be subsequently detected so as to sample and digitize the electrical signal. Nonlinear optical elements can be located inside the interferometer to reduce the minimum detectable electrical input signal size. The interferometer can contain more than two arms to improve the tolerable dynamic range of the electrical signal. In some cases some outputs of the interferometer are dependent on the electrical input frequency while others have minimal frequency dependence, thereby allowing the frequency of the input electrical signal to be measured more easily. Ideally the modulator operates in a push-pull mode with a single electrode for the input electrical signal. Such a modulator can be constructed by using appropriate optical delay elements.
