ABSTRACT:
An all-optical integrated photonic clock, systems employing the same, and methods of making and using the same. Illustrative examples are provided based on silicon semiconductor technology that employs rectangular waveguides fabricated on SOI wafers. In some embodiments, the clock can provide an optical timing signal. In some embodiments, the clock can provide a jitter-free electrical signal derived from the clock by use of a high speed photodetector.
