Good for you RFK! I’ve traded a few shares on spikes and bought them back on dips. But never traded my core position. I had a friend who sold his entire stake at $1.60 after realizing a 100% gain, only to see the price rocket up to $17 the next couple of weeks. Ooops!

Another person asked me whether r33 affects the size of the modulator. The answer is Yes.

Here’s a bit of an elaboration on the size aspect…

If you notice the units of r33 (pm/V), it has length as one of the units. It is a measure of how long the electrodes need to be for a given voltage to modulate the signal. In other words, it’s a measure of the effectiveness of the modulator material.

The more “effective” the material, the less of it you need…and the shorter/smaller you can make the modulator.

Also, a modulator is actually a phase shifter that operates at optical frequencies. R33 effectively determines how much phase shift you can get for a given voltage across your electrode.

Vpi is the voltage the causes a “half wave” (peak to null) in the amount of phase shift within the modulator.

Consequently, there is yet another tradeoff in modulator design. The trades are Vpi vs insertion loss/bandwidth vs power dissipation vs size.

The excellent team Dr. Lebby has put together appear to be very successfully navigating these various design parameters. The only thing that could make me happier is an uplist to Nasdaq and a NR of our first deal.
