Abstract
A commercially attractive arrangement for monolithic integration of a nonlinear optical polymer transverse electro-optic device for high data rate optical signals on an electronic integrated circuit chip. The invention provides for conductive polymer sheet layers immediately adjacent to an optical signal transmitting nonlinear optical polymer core layer. Electrically passive polymer cladding layers are also provided adjacent to the conductive polymer sheet layers to achieve lower optical signal losses. The combination provides a reduced nonlinear optical polymer core layer poling voltage, reduced device length, and 5 VDC or less controlling voltage, allowing inclusion into electronic integrated circuit chips of a size compatible with multichip module integration.
