In the last public presentation (Oppenheimer's 5G Summit: Wireless and Cloud Convergence) Suresh expands upon POET’s high performance capabilities. 

The architecture, the optical interposer medium and advanced packaging combine to enable the POET platform  to operate at very high speed with very low loss. We are all aware that POETs optical side provides for very low loss operation which is of the utmost  importance to reduce the energy requirements of the optical engines. But to completely unlock the photonic  capabilities of the optical engine the electrical pathways and metallic bonds that connect multiple dies need to have very low impedance to allow for low loss high frequency operation. POET’s waveguides are speed agnostic but to fully utilize these waveguides electronic communication needs to utilize the best that industry has to offer in combination with the optical interposer.

Suresh:

This is one of the things that we're seeing very clearly, even now with our initial deployment of products is that the interposer is such a low loss medium and when I say low loss, not just low optical loss but low RF lost right. Low electrical loss that you know we're able to operate these products at approximately 30% lower power power consumption of what might conventionally be achievable or possible. And so you know it's not just purely a cost benefit, it's not just purely a scale benefit you do get some performance benefits as a consequence of the integration and as a consequence of that, you know packing if you will, of the closeness or proximity that is able to be brought between the electronics and the optics  as a consequence of the integration. 

Ric Schafer:

Is there anybody else doing flip-chip or anything close to the sort of what you just described?

Suresh:

There are a lot of people attempting to do what we are doing but we are the only ones in the world that have been successfully able to do it with extremely small directly modulated lasers. So there are a lot of companies who do flip-chip attach of continuous wave lasers. And you know there are no new products out yet,  but there is activity in the industry. 

What we've been able to do is to apply this technology to this field of directly modulated lasers. And so we are the only ones in the world doing a fully integrated optical engine for the 100 gig, 200 gig and expandable to 400 gig using directly modulated lasers.  Historically directly modulated lasers have become, you know, over time, the laser of choice if you will. So I think you know people start out with various types of optical devices and then overtime converge to using what are called DML lasers in most of the applications. We believe that by having a platform that enables the use of these types of ultra small, ultra low power devices in optical communications allows us to not only provide competitive solutions at 100 and 200, but working with the right partners in the optical supply chain we can extend these solutions using DML lasers all the way to 1.6 or even two terabits per second, which without our platform is just simply not conceivable. I mean, you know, the road map for DML lasers would end at 400 gigabytes per second if it weren't for the integration possibilities that the POET interposer provides, so it it does add that dimension, which is an extension of a an otherwise ending road map to something that is substantially more beneficial to the industry,  in terms of a very very high throughput data communication links.
