Title: Optical fiber amplifier having a controlled gain
Inventor: LUTZ DIRK
IPC: H01S3/06
Filed: 1998-06-15
Granted: 2000-08-01
Abstract: An optical fiber amplifier for WDM-signals comprises an active optical fiber (1, 3) pumped with pumping light from a pump source (17). In order to give the amplifier a constant gain for the WDM-signals irrespectively of the number of active WDM-signals an additional light source (29) is arranged to inject, when required, extra light into the active optical fiber, at least in a portion (3) thereof, through a power combiner (27). The injected light has a wavelength different from that of the WDM-channels and preferably longer so that it will not cause an amplifying or pumping effect in the active optical fiber but so that it still can be amplified in the active fiber. The light source (29) is controlled by a signal derived from an output power measurement device (23) so that it will inject extra light when a WDM-channel becomes inactive. The power of the extra light is thus selected to saturate the optical fiber amplifier at a constant gain irrespectively of the number of signal channels, i.e. of the total power of the input light signals. A light filter (18) can be connected to the output end of the active optical fiber (1, 3) to block light having a wavelength corresponding to the wavelength of the light issued from the light source (29). Controlling the gain by this injection of ""extra signal light"" is much quicker than controlling the power of the pumping light.

Title: Two-step fabrication of metal barrier layer
Inventor: LIAU JUNG-JR
IPC: H01L21/768
Filed: 1999-04-09
Granted: 2000-12-11
Abstract: This invention relates to a method of forming a metal barrier layer by two steps. As a metal plug is formed, the dielectric layer under the barrier layer might be cracked because of rapid thermal process after the barrier layer is formed in a contact hole, and said barrier layer is also cracked. Another barrier layer is formed in this invention by physical vapor deposition to fill the crack of the barrier layer formed due to rapid thermal process, such that when it is necessary to form conductive plugs afterwards, conductive matters can be prevented from remaining in the crack which may lead to short circuits between plugs. After this step of this invention, it can then proceed depositing conductive plugs and etch back to form plugs, and then follow common processes to complete the fabrication of a semiconductor element.

Title: Digital reception with radio frequency sampling
Inventor: LIPKA DIETMAR
IPC: H04B14/06
Filed: 1999-08-04
Granted: 2001-04-21
Abstract: A radio frequency signal is received by using a sigma-delta analog-to-digital converter to sample the radio frequency signal at a sampling rate and to generate therefrom 1-bit digital samples representing a digital intermediate frequency signal. The intermediate frequency signal is demodulated to generate in-phase and quadrature samples. Demodulation may be performed by generating a first mixed signal by combining the 1-bit digital samples representing the intermediate frequency signal with a first sequence representing a cosine mixing signal; generating a second mixed signal by combining the 1-bit digital samples representing the intermediate frequency signal with a second sequence representing a sine mixing signal; and decimating the first and second mixed signals to generate the in-phase and quadrature samples. In alternative embodiments, the intermediate frequency signal is directly converted to in-phase and quadrature signals by using bandpass decimation filtering to subsample two time-shifted sequences of the intermediate frequency. In another alternative, the sigma-delta analog-to-digital converter uses subsampling to convert the radio frequency signal to a first intermediate frequency, and a decimation filter is used to further convert the signal to a second intermediate frequency. An IQ demodulator then reconstructs the in-phase and quadrature signals from the second intermediate frequency signal.
