"Since announcing our successful demonstration of a functional Vertical Cavity Surface Emitting Laser (VCSEL) for our integrated GaAs opto-electronic platform in early April, we have continued to make progress on performance optimization as part of our development effort to create a single-chip transceiver optical engine for the short-reach Active Optical Cable (AOC) market."

The above tune hasn't changed much.  Still trying to optimize, and I have no idea how valuable this is in the current stage of "optimization."
