VIPA based chromatic dispersion and dispersion slope compensating apparatus |
摘要 |
<p>In a chromatic dispersion and dispersion slope compensating apparatus according to the present invention, a WDM light which has been angularly dispersed to a first direction by a VIPA plate, is angularly dispersed to a second direction vertical to the first direction by a diffraction grating, and optical signals of respective wavelengths output from the diffraction grating are reflected by any one of a plurality of three-dimensional mirrors having reflective surfaces of curved shapes different from each other, to be returned to the VIPA plate. Thus, with a simple control mechanism in which the plurality of three-dimensional mirrors are moved to only the second direction, an apparatus capable of variably compensating for the chromatic dispersion and the dispersion slope independent of each other can be provided.</p> |
