Claim 0:
1. A modulator comprising:
at least one passive/active modulator unit comprising:
a passive waveguide extending a first length between an upstream passive end and a downstream passive end and having a width that is substantially maintained along the first length; and
an active portion extending a second length between an upstream active end and a downstream active end, wherein the active portion comprises a tapered active waveguide optically coupled to a portion of the passive waveguide; and

at least one additional passive waveguide coupled to the upstream passive end and the downstream passive end via one or more beam splitters and/or beam combiners, wherein a beam combiner of the one or more beam splitters and/or beam combiners is configured to couple a first beam output by the downstream passive end with a second beam to cause interference of the first beam and the second beam.
