Abstract

See full text

An apparatus comprised of a cascaded series of optical modulators addressed by a multi-bit digital word with each optical modulator in the cascaded series being responsive to a single bit in the multi-bit digital word and wherein each of the optical modulators in the cascaded series of optical modulators doubling in effective optical length as a bit index of the bit of the multi-bit digital word to which it is responsive increases by a bit index value equal to one. The apparatus may be used with a prior art analog optical modulator and an associated ADC, having a fixed bit width, to extend the number of bits beyond the fixed bit width that the ADC and analog optical modulator prior art combination can otherwise operate.
