Method And Apparatus For Controlling Modulator Phase Alignment In A Transmitter Of An Optical Communications System
View pageUS Patent:
20050002675, Jan 6, 2005
Filed:
Jul 2, 2003
Appl. No.:
10/610870
Inventors:
Harshad Sardesai - Ellicott City MD, US

Abstract:
A method and apparatus for controlling phase alignment in a modulator of a transmitter in an optical communications system utilizes an RF power signature to tune phase alignment. A portion of the optical signal is tapped and converted to an electrical signal. An electrical band-pass filter and RF detector examines a narrow slice of the RF spectrum and utilize the detected RF power to control phase alignment between the data modulator and pulse carver. Another portion of the optical signal is multiplied by the pulse carver clock, filtered and integrated in order to generate a second phase control signal for controlling the relative phase of a dual arm modulator being used as the pulse carver in one embodiment.
