Abstract: Casing (15) is installed in a well in a folded collapsed condition by uncoiling it from a reel (87). Two strings of tubing (27, 29) extend continuously through the collapsed casing. One of the strings of tubing (27) is connected to a cement shoe (19) at teh lower end of the casing. An opening tool (31) is located above the cement shoe (19) and includes a piston (33).  The other string of tubing (29) extends to a pressure chamber (35) that is between the piston (33) and the cement shoe (19). After the casing (15) is lowered with a running tool to the desired depth, cement is pumped down the first string of tubing (27), which flows back up the annulus surrounding the casing. A liquid is then pumped down the second string of tubing (29) into the pressure chamber (35), causing the piston (33) to push the conical forming head upward (38, 39) relative to the casing (15) and the strings of tubing (27, 29). The forming head (38, 39) opens the casing (15) from the collapsed condition into a cylindrical configuration. The running tool (55) retrieves the strings of tubing and the opening tool (31) at the conclusion of the opening and drifting process.

Abstract: An optical wavelength converter including first and second semiconductor optical amplifiers, an input optical pulse signal having a first wavelength .lambda.1 and a non-modulated optical signal having a second wavelength .lambda.2 are made incident upon the first semiconductor optical amplifier. Propagation constants of the first and second semiconductor optical amplifiers are determined such that a propagation constant difference .DELTA..beta. between the first and the second semiconductor optical amplifiers when only the optical signal having the second wavelength .lambda.2 propagates along the first semiconductor optical amplifier is smaller than a propagation constant difference .DELTA..beta. when both the input optical pulse signal and non-modulated optical signal propagate along the first semiconductor optical amplifier. During a lower power level of the input optical pulse signal, an amplified optical output signal having the second wavelength .DELTA.2 emanates from the second semiconductor optical amplifier due to the optical coupling, but during a higher power level of the input optical pulse signal, the optical coupling between the first and second waveguides is substantially released and no optical signal is emitted from the second semiconductor optical amplifier.

Title: Modulation format adjusting optical transponders
Inventor: TAYLOR MICHAEL G
IPC: H04B10/29
Filed: 1998-05-29
Abstract: The present invention provides a modulation format adjusting optical transponder for receiving an incident optical signal of a first modulation format and outputting an optical signal having a different modulation format. The transponder includes an optical-to-electrical conversion element configured to receive an information-bearing optical signal having a first modulation format and output an electrical signal corresponding to information from the incident optical signal. The transponder includes a laser for outputting an optical carrier signal at a selected wavelength and a modulator communicating with the optical-to-electrical conversion element and with the laser. The modulator places the information from the incident optical signal onto the optical signal output by the laser, creating a modulated optical output signal having a second modulation format different from the first modulation format. Advantageously, the optical system of the present invention can take optical signals in a common modulation format, such as amplitude modulation, and output optical signals in a power-flat modulation format, such as frequency shift key (FSK) modulation. The modulation format adjusting optical transponders of the present invention can be used as remodulators for wavelength division multiplexed optical systems.
