Stabilized thermally tunable optical waveguide devices and communication systems employing them |
摘要 |
<p>In accordance with the invention, a thermally tunable optical waveguide device is stabilized against ambient changes. Specifically, a feedback signal derived from a temperature-dependent resistance is used to stabilize the device with respect to ambient changes that could otherwise alter the temperature. Specific embodiments include resistance-heated tunable gratings. <IMAGE></p> |
