Title: Hybrid optical amplifier having improved gain tilt
Inventor: NEWHOUSE MARK A
IPC: H01S3/16
Filed: 1997-09-18
Abstract: PURPOSE: A hybrid optical amplifier having improved gain tilt is provided for changing nearly spectrally uniformed over a range of gain values compared to the constituent doped fiber in the aggregate of the hybrid device. CONSTITUTION: A hybrid, Er(erbium) doped fiber amplifier device has a dynamic gain tilt that is less than the gain tilt of any of the constituent fibers. The hybrid-amplifying device has at most one less pumping source than the number of constituent waveguides of the device. The hybrid device automatically provides an effective change in the pump distribution among the constituent doped waveguide sections so as to achieve a readjustment of the relative gains of the constituent sections. As such, a change in the aggregate gain of the hybrid device will be as nearly spectrally uniform as possible over a range of gain values compared to the constituent doped waveguides. A method for constructing a hybrid optical amplifying device having improved dynamic gain tilt is also provided.

Abstract: PURPOSE: A telephone response stand-by apparatus and method is provided to shorten the time of stand-by status by diversifying an information signal to request a calling subscriber to wait for a called subscriber's response and providing fractionated information signals to the caller according to circumstances. CONSTITUTION: When a call is received to a called subscriber's wireless terminal(300) from a calling subscriber but the called subscriber is placed in a difficult situation to receive the call, the called subscriber pushes an AR(Auto Response) button. The wireless terminal(300) searches for various response messages stored in a lookup table(160) connected to a switching part(130) to confirm whether the auto response message allocated to the incoming call. If there is no specially allocated message in the lookup table(160), the wireless terminal(300) regenerates a common message. In case that the lookup table(160) is storing the specially allocated message, the wireless terminal(300) regenerates the message of the associated voice message address so that the calling subscriber can listen to it. At this moment, the LED of the AR button is switched on and off to indicate that the calling subscriber is in stand-by status while the calling subscriber listens to the regenerated message.
