ASM beginning 22:50 on KEY Slide 28 ML important quotes,
"we had two major achievements here, this is a historic building block for the company, and it allows the company to participate at 1310 opportunities with MZ Modulators, these are WORLD CLASS RESULTS that now enable Short Reach Data Communications Applications within the Datacenter, and this allows us to really address some of the high volume opportunities there"
and
"We've also improved the performance over time of the Electro Optic Chromophore in terms of r33 for low power operation both with 1550nm (as you can see from the orange curve on that graph below ) as well as 1310nm (which is the blue curve) and you can see 1310 is now exceeding 200pm/V which actually allows extremely low voltage operation with excellent Stability at 85 degrees and you can see the r33 for 1550 has increased over the last 3 years to now above 165pm/V and approaching 200pm/V, and so these performance trends for both 1550 and now 1310 makes us a really interesting technology platform for the Data-Communications as well as the Tele-Communications market"

Note: 200pm/V enables LWLG "DRIVERLESS MODULATOR" << This is literally the holy grail of Photonics which has been sought after for 40 years with many the the giant companies spending Billions $$ to achieve but they ALL FAILED where LWLG HAS SUCCEEDED!
Slide 56 and 57 of April's SPIE Photonics presentation shows what is needed to achieve a 1 Volt driverless modulator at 100Gbps single lane.
The parameters are
-1 Volt or less
-5mm electrode length
-80GHz
-200pm/V
The press release states that we achieved the necessary 200pm/V in order to produce the device at 5mm which gives us an 80GHz (100Gbps) modulator at 1 Volt.
Below is slide 57 that shows these parameters in relation to one another.
Also below is the transcript of Dr. Lebby explaining slide 56 and 57.

"If you can eliminate drivers, you can eliminate power. You can eliminate ICs. And so, trying to operate things like polymer modulators at one volt or less means they're driverless. That is the really main motivation of actually using polymer modulators and very high speed and very low voltage.
In fact, when you start thinking about polymer platforms and designing modulators that are super high speed, some of the basic metrics come into play here. What we do know is that frequency response of these modulators is inversely proportional to the electrode length. So if you make these devices shorter and smaller, you can get higher speed, more gigabits per second.
But unfortunately, the V pi, the voltage is also inversely proportional to electrode length. And so, when you go to smaller devices you get larger voltages. And really, you want to keep the power down.
The only variable that is free is what is known as the r33, which is electro-optic coefficient of the polymer. If you can increase the r33, then you can have a short electrode. You can have high gigabits per second. And you can keep the voltage in check.
And that's what this graph is showing, here. A larger r33, in terms of let's say 200 picometers per volt, is the key to high performance and low voltage. Having expertise in designing chromophores, electro-optic chromophores that are polymer-based is one of the secrets in being able to have a very high bandwidth modulator, working at very low voltage for very low power consumption."
