Title: Analog optical switches using an integrated machzehnder interferometer having a movable phase shifter
Inventor: AL-HEMYARI KADHAIR
IPC: G02B6/42
Filed: 2000-11-22
Granted: 2001-08-21
Abstract: Optical devices employing a Mach-Zehnder interferometer (""MZI"") device having a phase shifter provided in one arm that enables the construction of significantly smaller optical devices than typical photonic devices, and significantly reduces the amount of on-chip real estate occupied by such devices, while not affecting the ability of such devices to introduce a predetermined phase shift in an optical signal. The present invention takes advantage of the extremely small mechanical actuators which can be fabricated using small-scale fabrication techniques, and so significantly reduces the room needed on a chip for optical switches. These more compact switches require less chip space and so provide for denser integration of a plurality of optical devices in an optical component.

Title: Pump power control for optical fiber amplifier
Inventor: MCNAMARA THOMAS WILLIAM
IPC: H04B10/17
Filed: 2000-12-18
Granted: 2001-12-01
Abstract: A gain-controllable optical fiber amplifier having an input for receiving an optical signal and an output for providing an amplified optical signal. A first gain stage is coupled between the input and output and includes a first fiber and a first pump. A second gain stage is coupled in series with the first stage and includes a second optical fiber and a second pump. The amplifier includes a pump controller for controlling the first and second pumps and adjusting the power output of the first and second pumps to maintain a substantially constant gain. The controller decreases the power output from each of the first and second pumps as a function of minimum output of each pump to minimize noise. Accordingly, the present invention advantageously controls the gain applied to an optical fiber in a manner that minimizes the amount of noise that may otherwise be introduced into the optical signal, especially when the input power is comparable to the backward amplified spontaneous emission of the amplifier.

Further, the set of code words belonging to the different coding states do not contain any code words in common. In one embodiment, n-bit code words of the first type end in ""00"", n-bit code words of the second type end in ""10"", n-bit code words of the third type end in ""01"", n-bit code words belonging to the states of the first kind start with ""00"", n-bit code words belonging to the states of the second kind start with ""00"", ""01"" or ""10"", and n-bit code words belonging to the states of the third kind start with ""00"" or ""01"". Furthermore, in the embodiments, the n-bit code words satisfy a dk-constraint to (2,k) such that a minimum of 2 zeros and a maximum of k zeros falls between consecutive ones. The coding device and method are employed to record information on a recording medium and thus create the recording medium. The coding device and method are further employed to transmit information. In the decoding method and apparatus, n-bit code words are decoded into m-bit information words. The decoding involves determining the state of a next n-bit code word, and based on the state determination, the current n-bit code word is converted into an m-bit information word. The decoding device and method are employed to reproduce information from a recording medium, and to receive information transmitted over a medium.

Inventor: VANLIER GERARDUS JOHANNES JOSE
IPC: H05B41/292
Filed: 2001-03-15
Granted: 2003-02-01
Abstract: A projection system is provided with a square-wave current light source and a color wheel with differently colored segments. The lifetime of the light source is long since the square-wave current constantly changes polarity a constant power is supplied to the light source and, before changing polarity, a current pulse is each time provided, driving the square-wave current to a predetermined strength which is larger than the current strength in between the current pulses. In the course of time, the amount of power in the current pulses increases relative to the amount of power in the current in between the current pulses. By controlling the timing of occurrence of the current pulses to constantly coincide in time and, on average, an equal number of times with all colors of the color wheel, the position of the white color point is independent of the period of time of use of the light source.

Abstract: There is provided a method for using K value to compensate zipper image and calculating the K value, wherein the method for using K value to compensate zipper image comprises the steps of: first determining whether the n-th original pixel of the m-th line is obtained by scanning a master line. If the n-th original pixel of the m-th line is obtained by scanning the master line, the n-th original pixel of the m-th line is compensated to be a value obtained by subtracting the sum of the (n-1)-th original pixel of the (m-1)-th line and the (n+1)-th original pixel of the (m-k)-th line from the n-th original pixel of the m-th line, and multiplying the same with K. If the n-th original pixel of the m-th line is obtained by scanning a slave line, the n-th original pixel of the m-th line is compensated to be a value obtained by subtracting the sum of the (n-1)-th original pixel of the (m+k)-th line and the (n+1)-th original pixel of the (m+k)-th line from the n-th original pixel of the m-th line, and multiplying the same with K.

Then, the wet bench machine is informed so that the machine can respond with an adequate reaction. Or, repetitive image uptake and the subsequent analysis and identification are performed. This invention can prevent wafer damage from subsequent wafer fixation and reduce time consumed for machine recovery. Therefore, up-time and productivity of the machine can be increased correspondingly.
