Abstract
An optical modulator drive circuit provides a different approach to driving an optical modulator than presently employed, resulting in a reduction in power dissipation of the drive circuit by as much as 80%. Therefore, this invention dissipates as little as 20% of power of the present drive circuits known in the art. The optical modulator may be a semiconductor electro-absorption modulator but the principle of the invention can be applied any other type of electro-optic modulator that relies on a voltage to modulate an optical signal.
