Appl. No.:

09/519654

Inventors:

Igal M. Brener - Westfield NJ
Benny Peter Mikkelsen - Atlantic Highlands NJ
Karsten Rottwitt - Basking Ridge NJ
Jason Blain Stark - Holmdel NJ

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H04B 1000

US Classification:

398160, 398150, 398157

Abstract:

An optical transmission system is formed to include an optical phase conjugator at alternate repeater sites to minimize the presence of four-wave mixing and other Kerr effect nonlinearities in systems using optical fiber transmission paths (particularly in systems using DWDM and launching relatively high power signals into the low dispersion fiber). Raman gain is included in each fiber span (or in alternate fiber spans) so as to provide a ânegative absorptionâ along the length of the fiber and thereby provide for essentially symmetrical power distribution along the length of each span, where the presence of such a symmetric,power distribution on each side of an optical phase conjugator has been found to significantly improve its performance.

International Classification:

G02F 1/01
G02B 26/00

US Classification:

359239

Abstract:

A method and apparatus is provided for controlling the bias point of a Mach-Zehnder modulator. The method begins by applying a dither signal to a DC bias that is applied to a Mach-Zehnder modulator. A component of an optical output signal provided by the Mach-Zehnder modulator that is synchronous with the dither signal is detected. The dither signal is adjusted to maintain the detected component of the optical output signal at a substantially constant value.

Appl. No.:

Inventors:

Jason Stark - Holmdel NJ, US

International Classification:

H04B010/04

US Classification:

398/182000

Abstract:

A filtered three-level transmitter is provided by filtering a binary electrical drive signal to produce a unit modulation pulse spanning four-bit-periods and describable by three parameters. One or more of the three parameters of the unit modulation pulse are adjusted to optimize a figure of merit associated with performance of an optical transmission system. A three-level electrical drive signal is then generated from the unit modulation pulse for input to a Mach-Zehnder modulator. The three parameters of the unit modulation pulse are each defined over a half-bit period and together are sufficient to describe a line-coded transmission eye diagram. The parameters are adjusted so that an optical transmission system in which the inventive transmitter is utilized is optimized with a set level of net chromatic dispersion.
