other that he's not at ODIS anymore, his CV confirms they indeed hit 50nm earlier in the summer, indicates 10x FET gate improvement, clues about POET's recipe & equipment, and other specific, detailed technical information that may be of value to hostile interests.

amongst other things, input gate node capacitance is crucial to the performance of high bit-rate receivers, i.e., capacitances of the FET gate, the pin, and any strays from bond wires and pads. when things are monolithically integrated as with P[O]ET, the bond pads and wires are no longer present, so strays are greatly reduced. then, further improvents are obtained by reducing pin capacitance and FET gate width. result: higher speed and/or better sensitivity.
