Hi Crossy, Thanks for the tune up. Low voltage appears to be one big goal and a KVHI advantage. All efforts so far just in the infancy of long term mega trend.IMHO Bob

<<The huge disadvantage is the high bias voltage (>100V) needed to drive such a modulator at 40Gbit/sec. The voltage requirement increases with speed.>> Hi Crossy. That's not accurate for all materials. You must be referring to modulators based on crystalline materials like InP or LiNbO3. The KVH modulator that Robert was referring to uses polymers, and runs at either 10Gbps or 40Gbs and uses only 3V DC. Other specs like Optical loss and extinction ratio are also superior to other materials. kvh.com kvh.com The price is likely to be much lower too, as they don't use an Electro-Optic chip - it's all inside the fiber photonicfiber.com
