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.

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： This invention demonstrates the methods that use semiconductor laser amplifier (SLA) as a wavelength discriminator, as well as several apparatus designed using these methods. The functions of the invented apparatus include wavelength measurement, wavelength tracking, wavelength comparison, and wavelength stabilization and control of lasers. The key concept for which these methods and apparatus work is the variation of the transparent current of a SLA with the wavelength of an incident light. The transparent current of a SLA can be easily detected from the induced voltage across the diode junction when the incident light is intensity-modulated. The incident wavelength can be accurately determined by measuring the transparent current. These methods and apparatus are expected to be very useful in wavelength display for photonic instruments, wavelength control and wavelength registration for photonic networks, and wavelength stabilization for laser diodes. Since the SLA can be monolithically integrated with semiconductor lasers.
