摘要： An add-drop wavelength filter is described which separates specific wavelength components from optical signals propagating through an optical waveguide or adds specific wavelength components thereto. In general, add-drop wavelength filters serve to separate or add specific channels in channels comprising several different wavelengths in a wavelength division optical communication system, and require good wavelength selectivity, stability and etc. Up to now, several types of add-drop wavelength filters are proposed, however disadvantageously they were not stable or were difficult to fabricate. The add-drop wavelength filter of the present invention comprising a mode discrimination coupler, Bragg gratings in which mode conversion occurs and etc., utilizes mode conversion in a dual mode waveguide and has low loss and stability. Furthermore, devices included in the add-drop wavelength filter are conventionally used, thereby resulting in easy fabrication, and the application fields of the devices can be easily expanded by apodization, chirping, or etc. of the Bragg gratings.

摘要： An optical amplifier comprises a wavelength tunable filter, one or more optical gain stages, and a controller for controlling a spectral profile of the wavelength tunable filter in response to a measured spectral characteristic of the amplifier. The controller may also control gain of the gain stage(s). The controller determines the filter spectral profile necessary to obtain a desired amplifier spectral characteristic. The spectral characteristic may, for example, be a power spectral output of the amplifier or a gain profile of the amplifier. The amplifier may incorporate a dispersion compensator. The controller may control a spectral profile of the wavelength tunable filter and gain of the dispersion compensator. A tunable fiber light source is also described.

摘要： The present invention relates to a wavelength-swept laser and a method for generating laser output. The wavelength-swept pulse laser according to one aspect of the present invention uses spontaneous mode-locking to produce a pulse output with the center wavelength continuously varying with time. On the contrary, the wavelength-swept laser according to another aspect of the present invention suppresses mode-locking to produce continuous output by tuning the filter frequency change speed to the frequency shift speed of the frequency shifter. The lasers of the present invention are applicable to optical sensing or WDM optical communication.
