Abstract:
An electrooptic clad waveguide comprising an optical waveguide core defining a primary axis of propagation z, a first cladding region offset from said z axis in a first direction along an x axis perpendicular to said z axis, and a second cladding region offset from said z axis in a second direction along said x axis, wherein:said optical waveguide core comprises a substantially non-electrooptic material defining a refractive index n1; said first cladding region comprises an electrooptic polymer defining a refractive index that is less than n1; said second cladding region comprises an electrooptic polymer defining a refractive index that is less than n1; said electrooptic polymer of said first cladding region is configured such that its polar axes are oriented in a direction substantially opposite a direction in which polar axes of said electrooptic polymer of said second cladding region are oriented.
