摘要： The present invention relates to a constructing method and device for an optical passive component by using an improved structure of a Mach-Zehnder interferometer. This improved structure of the Mach-Zehnder interferometer is composed of two MMI beam splitters, a curved channel waveguide and a periodic segment waveguide for being separately used as the beam-splitting components, the curved arm and the straight arm of the Mach-Zehnder interferometer. In the inventive MMI beam splitter, a sub-area in the MMI waveguide is a periodic segment waveguide having a plurality of segments. By adjusting the number of the segments of the periodic segment waveguide in the MMI waveguide, the beam-splitting ratio of the MMI beam splitter can be arbitrarily adjusted. By adjusting the segment period and the duty cycle of the straight arm of the Mach-Zehnder interferometer, the required length of the straight arm can be efficiently shortened.

摘要： An apparatus and method for measuring a coherence sampling quality-factor (Q-factor) are provided, which are used to monitor quality of an optical signal in an optical network in real time. The quality is evaluated by a Q-factor. A laser diode and a wavelength converter are used in the apparatus to achieve wavelength coherence and amplification of the optical signal. Furthermore, the laser diode and an optical switch are used together to obtain an optical pulse that can be utilized to sample the optical signal. Therefore, after entering into an optoelectronic converter, a baseband signal in the optical signal is reconstructed through the amplification of the optical signal and the coupling of the optical pulse, so as to detect the Q-factor and to monitor the quality of the optical signal.

摘要： An all-optical label swapping system and method superimposes a low-speed ASK label on top of a high-speed DC-balanced-line-coded ASK payload. An old ASK label is erased by modulating the combined payload and label signal with the inverse of the received ASK label. This ASK labeling technique requires only low speed external modulators and low speed optical receivers to perform the label swapping mechanism, and does not require sophisticated optical components.

摘要： A non-sampling-based Q-factor measuring apparatus and method use a power conversion module to transform the power variation of inputted optical signals in time domain into the variation in other domains, such as optical wavelength, optical polarization and different output ports of optical elements. Taking optical wavelength as an example, different levels of power variation respond different outputs of wavelength variation through the use of a power-to-wavelength conversion module. An optical filter then separates the inputted optical signals with different wavelengths. The power average of a wavelength for its corresponding optical signals is further calculated by a photo detector. Thereby, the information of the power variation for the inputted optical signals at levels 1 and 0 can be obtained, and the Q-factor for the inputted optical signals is easily measured.
