Photonics Guy, Richard, going through the ECOC presentation and have a couple of technical questions

1) Slide 38 "Direct Drive" Optical Modulators

the takeaway green box says >>

Low voltage operation means: ‘direct drive’ ? driverless

So, what normally drives the modulator, a laser diode right? So originally I thought LWLG's "Direct Drive" was the fact it was being developed on InP where "the laser comes for free", but I think because the Voltage is so low the modulator maybe doesn't require a laser to drive it, is this possible?

2) Slide 41 Small size enables transceiver platforms

I keep looking at this slide in amazement because it shows the LWLG device so tiny compared to today's pluggable TXRX device and when you look to the top right of the slide it would appear that this is perhaps LWLG's first PIC proto, is that possible? and it shows 130GHz just under it, is it possible that this is a LWLG PIC proto that would fit in the tiny rectangle shown above today's pluggable device?

the takeaway green box says >>

5mm, 100Gbaud ? High density, small footprint TxRx


Ok, so then if the PIC modulator doesn't need a laser driver it could be possible that the P2IC Platform could be a reality sooner rather than later? and would it also be possible that if it were a P2IC that LWLG could have designed and fabricated a proto already in-house?

Role of polymers will accelerate quickly (slide 53)
