Rick,
It actually starts on the page before. Here is the whole thing from p 19-20:
In August 2013 in a combined effort of the Company’s chemists, the University of Colorado, Boulder, and a third
party research group we successfully fabricated Silicon Organic Hybrid (SOH) slot waveguide modulators. The devices
utilized an existing modulator structure with one of our proprietary electro-optic polymer material systems as the enabling
material layer. In October 2013, we confirmed the functionality of the SOH slot waveguide modulators as operating
prototype devices. These first-generation devices have achieved greater electro-optical activity and dramatically lower
drive voltage than industry standard modulators based on inorganic materials. We continued this effort in 2014 and have
signed an agreement with the third party research group to continue our collaboration through 2015.
In November 2013, preliminary testing and initial data on our SOH slot waveguide modulators demonstrated several promising characteristics. The tested SOH chip had a 1-millimeter square footprint, enabling the possibility of
sophisticated integrated optical circuits on a single silicon substrate. In addition, the waveguide structure was
approximately 1/20 the length of a typical inorganic-based silicon photonics modulator waveguide. With the combination
of our proprietary electro-optic polymer material and the extremely high optical field concentration in the slot waveguide
modulator, the test modulators demonstrated less than 2.2 volts to operate. Initial data rates exceeded 30-35 Gb/sec in the
telecom, 1550 nanometer frequency band. This is equivalent to four, 10Gb/sec, inorganic, lithium niobate modulators that
would require approximately 12-16 volts to move the same amount of information. Our material also operates in the 1310
nanometer frequency band, which is suitable for data communications applications.
