METHOD FOR COMPENSATING FOR WAVELENGTH SHIFT IN WAVELENGTH SELECTIVE SWITCH, AND DEVICE THEREFOR |
摘要 |
<p>A method for compensating for a wavelength shift in a wavelength selective switch (WSS), and a device therefor. The device comprises a fixed seat (301) as well as a rotation beam (304) and a compensation block (302) that have different thermal expansion amounts, the rotation beam (304) and the compensation block (302) being fixedly adhered to the fixed seat (301). In the method, a combined structure of the rotation beam (304) and the compensation block (302) with different thermal expansion amounts is adopted; the combined structure rotates by means of different expansion amounts generated by the rotation beam (304) and the compensation block (302) at the same external temperature, and further drives an optical element of the WSS to rotate, hence compensating for a wavelength shift of the WSS. The method is safe and reliable; the device has a simple structure, and is convenient to encapsulate, is applicable to various WSS optical paths, and does not affect advantages of the optical path structure of the WSS.</p> |
