摘要:
A self-starting mode locking soliton device includes a first optical port to accept an input coherent light. A second optical port provides an output comb of a plurality of wavelengths. A comb resonator with optical Kerr nonlinearity and anomalous group-velocity dispersion is optically coupled to both of said first optical port and said second optical port. The resonator includes an optical property of a negative nonlinear bistability to enable the self-starting mode locking of a Kerr soliton comb. A method of self-starting mode locking is described. A method of producing the negative nonlinear bistability is also described.

The present invention relates to method and system for displaying user activities based on geographical location information, and a computer storage medium, the method comprising: an SNS server obtaining personal activities information submitted by a first SNS user and the geographical location information of the first SNS user submitting the personal activities information; establishing a personal activities information database of the first SNS user according to the personal activities information, the geographical location information and the identification number of the first SNS user, and storing the database in the SNS server; the SNS server searching for the friend list of the first SNS user in the database, notifying a second SNS user on the friend list of the first SNS user of the personal activities information, the geographical location information and the identification number of the first SNS user and displaying in the friend status of the second SNS user.
摘要:
A wireless communication network includes a central node and a plurality of sub-nodes including relay nodes and terminal nodes. A method for adaptively selecting a route for communications in the network includes: generating a global routing table of the network based on a predetermined criterion, by the central node independently or in cooperation with a part of the relay nodes; generating a local routing table of each of the sub-nodes based on the global routing table, and informing the local routing tables to the respective sub-nodes to store the local routing tables in the respective sub-nodes, by the central node independently or in cooperation with a part of the relay nodes, the local routing table including paths from the corresponding sub-node to adjacent nodes; and adaptively selecting, by the sub-node, a path from the local routing table thereof for communications according to a predetermined rule.
