| 英文摘要 | A temperature-compensated tunable optical waveguide grating device comprises a length of optical waveguide grating including an optical grating region, a guiding tube or frame mechanically coupled to the waveguide at one end of the grating region, and mechanically coupled to the waveguide at the other end of the grating region, a movable element responsive to control signals for applying adjustable strain across the grating region, thereby tuning the grating. The device further comprises a temperature-compensating element for modulating the strain in proportion to changes in temperature, thereby temperature compensating the device. Advantageously the waveguide is an optical fiber and the movable element is a movable magnet. The inventive device can reduce the temperature-dependent wavelength change to less than 0.5 nm/100 deg. C., and advantageously less than 0.05 nm/100 deg. C. In an advantageous embodiment, the packaging assembly also includes a fine wavelength-adjusting mechanism for post-assembly corrective tuning. The device is especially useful in WDM communication systems, particularly for adding or dropping channels, for dynamically gain-equalizing optical amplifiers and for dispersion compensation. |
