Abstract: A drive circuit for a direct modulated laser and a direct modulated optical transmitter. The drive circuit includes a service data drive unit, a voltage configuration unit, a monitoring data modulation unit, and a monitoring current generation unit. Output terminals of the voltage configuration unit and the monitoring data modulation unit are connected to a same input terminal of the monitoring current generation unit. An output terminal of the service data drive unit is connected to a current sink interface of the monitoring current generation unit, and is suitable for connecting a direct modulated laser. In the technical solution, a low-speed monitoring data signal is mixed into an average optical power signal of a high-speed service data light wave from the direct modulated laser, then is extracted from the received optical signal by a remote optical receiver, enabling the drive circuit to be remotely monitored.

Abstract: A method for manufacturing semiconductor elements by a metal lift-off process and a semiconductor element manufactured thereby, include steps of photoresist-coating, exposing, developing, metal-coating, and lift-off. A photoresist layer can be removed with a photoresist stripper. Meanwhile, the metal on the top of the photoresist layer can also be removed when the photoresist layer is removed. The circuit layout required for the semiconductor element can thus be completed without an etching process. In addition, by setting the process parameters, the contour of the photoresist layer can present a certain angle, so that the metal on the surface of the photoresist layer can be completely removed, which saves costs and improves competitiveness.

The method includes migrating the inventory data to a target data node. The method also includes migrating the incremental data, and during the migration when the unmigrated incremental data satisfies a preset write-lock condition, instructing the source data node to perform a write-lock operation on the to-be-migrated data shard and migrate unmigrated incremental data to the target data node. The method further includes, after the migration of the incremental data is completed, instructing a coordinator node to switch a route corresponding to the to-be-migrated data shard from the source data node to the target data node.
