Alignment Of In-Phase And Quadrature Data In Quadrature Phase Shift Keying Optical Transmitters

US Patent:
2012025, Oct 4, 2012
Filed:
Apr 1, 2011
Appl. No.:
13/078733
Inventors:
Sunil Kumar Singh Khatana - Sunnyvale CA, US
Lee Dardis - San Jose CA, US
Assignee:
OPNEXT SUBSYSTEMS, INC. - Los Gatos CA
International Classification:
H04L 27/20
US Classification:
375308
Abstract:
I/Q data skew in a QPSK modulator may be detected by sending identical or complementary data streams to I and Q channel PSK modulators, setting the relative carrier phase between I and Q to zero or π, and monitoring the average QPSK output power, where the data streams sent to the I and Q channels include streams of alternating ones and zeroes.

Mach-Zehnder Modulator Drive Level Optimization

US Patent:
2014001, Jan 16, 2014
Filed:
Jul 11, 2013
Appl. No.:
13/939489
Inventors:
Lee Dardis - San Jose CA, US
International Classification:
G02F 1/01
US Classification:
359239
Abstract:
A method for determining, by a modulator assembly, an optimal drive point for a Mach-Zehnder modulator (MZM). The modulator assembly applies an electrical modulation signal to the MZM to modulate an optical input signal and create a modulated optical output signal, the modulated optical output having a spectrum that includes a first and third harmonic. The modulator assembly measures the difference in magnitude between the first harmonic and the third harmonic as the amplitude of the electrical modulation signal is varied, and determines a value for the amplitude of the electrical modulation signal that corresponds to a maximum difference between the first harmonic and the third harmonic.
