    • A single-frequency semiconductor laser diode structure and a method for its fabrication. The structure includes a built-in etalon, which limits the frequency of operation of the device to a very narrow frequency band. For an edge-emitting diode, the etalon is formed over a cleaved end face of the semiconductor diode structure, and light is emitted from an opposed cleaved end face. For a surface emitting diode, the etalon is formed as an additional plurality of layers between a plurality of semiconductor layers forming the diode and a substrate on which the structure is formed. Transverse channels formed in the structure have side surfaces that act as mirrors, at least one of which is angularly inclined to the plane of the active region, to reflect light through the etalon layers and out through a parallel exterior surface of the structure. Multiple surface emitting lasers may be arrayed in closely spaced relation to each other, to form a powerful light emitting array.
    • 单频半导体激光二极管结构及其制造方法。 该结构包括内置的标准具,将器件的工作频率限制在非常窄的频带。 对于边缘发光二极管,标准具形成在半导体二极管结构的切割端面上,并且从相对的切割端面发射光。 对于表面发光二极管,标准具形成为形成二极管的多个半导体层和其上形成结构的基板之间的附加多个层。 在结构中形成的横向通道具有用作反射镜的侧表面,其至少其中之一与有源区域的平面成角度地倾斜,以反射光通过标准具层并且穿过结构的平行外表面。 多个表面发射激光器可以以彼此间隔紧密的关系排列,以形成强大的发光阵列。

    • The present invention provides methods of inter-technology handoff of a multi-mode mobile unit in a packet-switched communication system. One embodiment of the method includes establishing a call from a first application layer client in the first mobile unit using a first wireless communication link that operates according to a first wireless access technology. The method also includes sending, in response to detecting changing conditions of the first wireless communication link, a request to form a conference call including the first application layer client and inviting a second application layer client in the first mobile unit to join the conference call. The second application layer client uses a second wireless communication link that operates according to a second wireless access technology. The method further includes handing off the call from the first application layer client to the second application layer client.
    • 本发明提供了分组交换通信系统中的多模式移动单元的技术间切换的方法。 该方法的一个实施例包括使用根据第一无线接入技术操作的第一无线通信链路来建立来自第一移动单元中的第一应用层客户端的呼叫。 该方法还包括响应于检测到第一无线通信链路的变化条件,发送形成包括第一应用层客户端的会议呼叫的请求,并邀请第一移动单元中的第二应用层客户端加入会议呼叫。 第二应用层客户端使用根据第二无线接入技术操作的第二无线通信链路。 该方法还包括将呼叫从第一应用层客户端切换到第二应用层客户端。
