英文摘要	Wavelength-agile optical filters, suitable for wavelength-division-multiplexed optical communications networks, which provide for electrical or mechanical tuning to a known position or electrical parameter with precision in the selected center wavelength arising as result of the arrangements of a grid generator (246) and a channel selector (252). Within the embodiments of the invention, it may be used in a wide range of applications, such as, tuning an external cavity laser, selecting a wavelength for an add/drop multiplexer and providing channel selection and feedback for a wavelength locker, or be implemented in whole or in part of a gain medium (224). The invention may thus be utilized in telecom applications to generate the center wavelengths for any channel on the current International Telecommunications Union or other optical grids.
