The Dual Carrier LN Modulator
integrates 2 DP-QPSK LN modulators
onto 1 chip and 2 polarization beam couplers into 1 compact package to provide support for both 200G DP-QPSK and 400G DP-xQAM modulation formats.
By using the same ring resonator for both the wavelength control unit of the light source and the optical modulator
, Fujitsu Laboratories previously devised a structure that made the wavelengths of the light source and optical modulator
identical without the need for a thermal control mechanism.
In addition, engineering samples of 40Gb/s DQPSK and 100Gb/s DP-QPSK modulators
will become available in the fourth quarter of 2010, with Telcordia qualified volume production starting in the first quarter of 2011.
provide excellent linearity with higher input IP3 values (> +26 dBm).

Passing the stringent requirements of the Telcordia GR-468 is essential, as it demonstrates that the TFPS modulators
meet the long-term reliability standards required by today's telecommunication sub-system and system integrators.
Currently, Ashtiani is undertaking research in the area of direct carrier microwave modulators
for low cost mm-wave transmitters.
By using a successful Mach-Zehnder modulator
production flow, we were able to bring this product to the market quickly and we look to build upon these successes to further our disruption of the market.
Each RF input passes through a 15 dB coupler before entering a vector modulator
Raluca Dinu, GigOptix's Vice President and General Manager of GigOptix Bothell, states, "These successful tests prove that the LX8401 modulator
based on our proprietary TFPS technology demonstrates both reliable and competitive performance and we are excited to have customer validation of our low power consumption, small footprint and disruptive modulator
Mixers and power splitters using the Blue Cell designs have been manufactured for over two years, and this complete family of modulators
as well as a Blue Cell transformer have been introduced recently.
The outputs of the I and Q modulators
are then fed to a broadband combiner that accurately sums the I and Q vectors.
