Abstract
Traveling wave cascaded micro ring modulators (TW-CMRMs) are provided. An example TW-CMRM includes an optical bus, an electrical transmission line, and at least two micro ring modulators (MRMs) operatively coupled to the optical bus and the electrical transmission line. The electrical transmission line includes a cathode transmission line and an anode transmission line. The at least two MRMs are cascaded in a series connection, and the at least two cascaded MRMs include a first terminal and a second terminal respectively. The at least two cascaded MRMs collectively modulate a phase and/or an amplitude of an optical input signal received from an optical signal source.
