    • A method of fabricating a poled fiber and a dispersion compensator. The method including patterning to cover an etching-resistant material on the body portions of the cladding and on one end or both ends of the optical fiber excluding the portions to be grooved in the longitudinal direction, etching the bare portions of the cladding excluding the portions covered with the etching-resistant material, evaporating electrodes on the etched portions and applying a voltage to the electrodes, and inducing periodic poling generating optical phenomenon of the second-order nonlinearity to the optical fiber through the patterned electrodes. The compensator including a periodic poled fiber to generate a phase conjugate wave of a difference frequency between a pump light and a signal light received from a fiber coupler, and a filter to pass the phase conjugate wave coming out from the periodic poled fiber.
    • 一种制造极化纤维和色散补偿器的方法。 该方法包括图案化以覆盖在包层的主体部分上以及光纤的一端或两端的除了在纵向方向上被切槽的部分之外的耐腐蚀材料,蚀刻除了部分之外的包层的裸露部分 用耐腐蚀材料覆盖,在蚀刻部分上蒸发电极并向电极施加电压,并且通过图案化电极引起周期性极化产生对光纤的二次非线性的光学现象。 补偿器包括周期性极化纤维,以产生泵浦光与从光纤耦合器接收的信号光之间的差分频率的相位共轭波,以及滤波器,以使从周期极化纤维出来的相位共轭波通过。

    • Disclosed is a method for remotely controlling an operation of a mobile telecommunication terminal in preparation for a case of loss or theft of the mobile telecommunication terminal, which includes the steps of: (a) monitoring whether a lock setup instruction to enter the lock setup mode is received from the remote control server; (b) controlling a microprocessor included in the mobile telecommunication terminal so as to enter the lock setup mode, when the lock setup instruction is received in step (a); (c) monitoring whether a lock release instruction to enter the lock release mode is received from the remote control server; and (d) controlling the microprocessor so as to enter the lock release mode when the lock release instruction is received in step (c).
    • 公开了一种用于远程控制移动电信终端的操作以准备移动通信终端的丢失或被盗的情况的方法,其包括以下步骤:(a)监视是否进入锁定设置模式的锁定设置指令 从遥控服务器接收; (b)当在步骤(a)中接收到锁定设置指令时,控制包括在移动通信终端中的微处理器进入锁定设置模式; (c)监视是否从远程控制服务器接收到进入锁定释放模式的锁定解除指令; 以及(d)在步骤(c)中接收到锁定解除指令时,控制微处理器进入锁定解除模式。
