1. An apparatus comprising:
- a plurality of electrical drivers; and
at least one optical signal path comprising a plurality of sections, wherein at least one section comprises a plurality of sub-sections, wherein at least some of the plurality of sub-sections each comprise an optical modulating element, wherein at least some of the optical modulating elements each are coupled with at least one of said plurality of electrical drivers,wherein said each coupled electrical driver is configured to generate at least one electrical signal for modulating at least one of propagation properties of an optical signal through said at least one optical signal path, andwherein the electrical drivers are configured such that a time delay difference between the electrical signals generated by at least two electrical drivers coupled with the optical modulating elements of respective sub-sections within said at least one section of said at least one optical signal path is smaller than or equal to seventy percent of the time-of-flight of an optical signal through said at least one section of said at least one optical signal path.

Abstract
We disclose herein an optical apparatus comprising an optical signal path which is driven by a plurality of electrical drivers. The electrical drivers are configured to optimize delays between two adjacent electrical drivers. The delays are optimized such that power loss in the optical apparatus is reduced.
