Abstract: A tunable laser has a solid state laser medium having an optical gain region and generates coherent radiation through a facet. A lens collects the coherent radiation and generates a collimated light beam. Components of an external cavity include a reflective surface and an optical filter, the reflective surface reflecting the collimated beam back to the lens and the laser medium, the optical filter positioned between the reflective surface and the lens and having two surfaces with a thermally tunable optical transmission band within the optical gain region of the laser medium. The optical filter (1) transmits a predominant portion of the collimated beam at a desired wavelength of operation, and (2) specularly reflects a remaining portion of the collimated beam from each surface, the collimated beam being incident on the optical filter such that the reflected collimated beams propagate at a non-zero angle with respect to the incident collimated beam.

Abstract: This application is directed to a geographic information display method. While a first mobile device is executing an instant messaging application, it obtains its own geographic location information, a second mobile device's geographic location information, and a first timestamp at which the geographic location information is recorded. The first mobile device then displays an interactive map associated with the first timestamp on a user interface. The displayed map includes two marks that represent the locations of the first and second mobile devices, respectively, and instant messages exchanged between these two mobile devices are displayed on the map adjacent to the two marks. As the first mobile device obtains updated geographic location information in association with a second timestamp, it updates the location of the second mobile device while the mark corresponding to the first mobile device remains at the same location on the user interface.

Abstract: A server receives a group message from a first user account in a social networking platform, the group message to be sent to a plurality of user accounts, and determines whether the group message refers to one or more user accounts of the plurality of user accounts. For a respective user account referred to by the group message, the server sends a notification to a terminal associated with the respective user account, wherein the notification is rendered at the terminal in a first manner configured by the respective user account. For a respective user account not referred to by the group message, the server sends a notification to a terminal associated with the respective user account, wherein the notification is rendered at the terminal in a second manner configured by the social networking platform, wherein the second manner is different from the first manner.
