I agree with both KCC and Proto that the r33 is somewhere around 400pm/V. Today's NR is a really big deal. It is obviously geared toward industry rather than retail shareholders. I guarantee...industry is sitting up and taking notice.

Why is r33 such an important parameter? It is a measure of how effectively the modulator modulates. The higher the r33, the better or more effectively the modulator modulates the incoming data signal.

There is a tradeoff between Vpi (the voltage used to bias the modulator) and the useable bandwidth of the device. Useable bandwidth is affected by the amount of Insertion Loss through the modulator, and a higher Vpi reduces the amount of loss. However, a higher Vpi also results in the requirement to use expensive, power-hungry modulator drivers to boost the incoming data signal to the level of the Vpi. So it's a tradeoff. To get less loss and higher bandwidth, you need higher Vpi, but the higher Vpi causes significantly more power dissipation and expense due to the requirement to use an external modulator driver with its inefficient GaAs RF amplifier.

So, if we had a modulator that had very low loss and higher bandwidth at lower Vpi's, then both demands of low power dissipation and higher bandwidth are simultaneously realized. We're still able to get great bandwidth without the use of the power-hungry external modulator driver.

That's what this NR is all about. IMO, this is one of the most important NR's I've seen.
