So from the following statement in my previous post.

One of the problems with all solid state lasers is the maximum possible speed of modulation. Capacitance effects and effects caused by the (relatively slow) movement of charge carriers within the semiconductor limit the speed of modulation. External modulators are used at high speeds but this adds cost and complexity. Also signal strength is lost in the additional couplings required.

Co-packaging a laser and modulator chips fabricated on the separated wafers typically introduces 2- to 4-dB loss. This loss needs to be balanced by higher laser drive current resulting in higher power consumption.

So we know that POET will be using MZI (silicon) modulators and will also be using EAM modulators.

When we look at the statement above regarding the losses associated with packaging a laser with a modulator we can see the loss given as 2 to 4 dB which means the laser needs to be driven at higher energy to overcome these losses. You will recall that our new president talked about losses in an integrated optical engine typically being as high as 50%. As I recall POET’s solution reduces this loss dramatically and 90% efficiency comes to mind. So lower energy and losses means dramatically lower heat in an already heat efficient lateral layout of chip sets. And we all know that heat associated with the optical side must be tightly controlled to maintain wavelength accuracy (limit wavelength drift) so the information is within the receive window at the other end. Albeit this is less critical with POET’s athermal characteristics.

It really is a solution that has benefits at many levels. Let’s get the show on the road!

There are so many benefits to promote here that it is kind of mind boggling that the share price is where it is. Our time will come.

Remember that the strength of the optical interposer platform is the ability to mix and match different devices associated with different material sets in an automated CMOS friendly flow. I expect POET to be working with many suppliers of those devices which become modified to be optical interposer friendly.

Best of the season to everyone.
