NASDAQ: OCLR), a provider and innovator of optical communications solutions, has announced volume production of its lithium niobate (LiNbO3) Polarization Multiplexed Quad Mach-Zehnder
(PM-QMZ) modulators, the company said.
Because data is characterized by its I and Q components, four separate bit streams are required to drive Mach-Zehnder
I/Q optical modulators for both polarizations, as shown in Figure 1.
a leading provider of radio frequency (RF) and mixed-signal integrated circuits for cable and satellite broadband communications, the connected home, data center, metro, long-haul fiber networks, and wireless infrastructure, today announced the MxL9207, a quad-channel Lithium Niobate (LiNbO3) Mach-Zehnder
(MZ) modulator driver for next-generation 100Gbps optical DWDM coherent systems.
Implementation of optical switches using Mach-Zehnder
These modulation formats are possible to design with in parallel connected Mach-Zehnder
2009) interferometers; and Mach-Zehnder
interferometers (Liu and Kobayashi 1996; Bruneau 2001; Bruneau and Pelon 2003), including the optical autocovariance receiver, a modified Mach-Zehnder
interferometer (Schwiesow and Mayor 1995; Grund and Tucker 2011).
The acquisition will bring InP-based IQ Mach-Zehnder
modulators for 100G coherent applications to the buyer's portfolio of narrow-line width tunable lasers, enabling Finisar to offer a comprehensive portfolio of optical components, the buyer said.
In recent years, optical logic gates based on several different schemes, such as dual semiconductor optical amplifier (SOA) Mach-Zehnder
interferometer (MZI) [4-9], semiconductor laser amplifier (SLA) loop mirror [10,11], ultrafast nonlinear interferometers [12,13], and four-wave mixing process in SOA , are demonstrated and reported.
A novel frequency sextupling scheme for optical mm-wave generation utilizing an integrated dual-parallel Mach-Zehnder
modulator," Optics Communications, Vol.
Pulse carver needs an additional Mach-Zehnder
modulator which increases the cost of the transmitter design and will also reduce the power of optical signal, thus affecting the overall power budget of the optical system.
In a previous work  we proposed a broadband Mach-Zehnder
switch configuration based on three-waveguide couplers which guarantees a broadband operation compared to the conventional two-waveguide configuration.
In this paper, we propose a 1 x N (input x output) optical which includes three segments that in the first one both symmetric and asymmetric Mach-Zehnder
waveguides are used.
