Abstract: An optical modulation device includes a substrate. An optical waveguide is formed on the substrate. The optical waveguide exhibits an electro-optical effect. Parallel lines electromagnetically coupled with each other are formed on the substrate. The parallel lines extend at opposite sides of the optical waveguide respectively. The parallel lines are of a microstrip line structure. The parallel lines may alternatively be of a strip line structure or a coplanar line structure.

Abstract: An optical waveguide structure forms an MZI in proximity to an electro-optic material. A first (second) electrical input port is configured to receive a first (second) drive signal. The second drive signal has a negative amplitude relative to the first drive signal. A first (second) transmission line is configured to propagate a first (second) electromagnetic wave over at least a portion of a first (second) optical waveguide arm to apply an optical phase modulation. A drive signal interconnection structure is configured to provide a first electrical connection between the first electrical input port and an electrode shared by the transmission lines, and a second electrical connection between the second electrical input port and respective electrodes of the transmission lines; and is configured to preserve relative phase shifts between the drive signals. Input impedances at the first and second electrical input ports are substantially equal to each other.

Abstract: Performance improvement of an all-optical analog-to-digital converter (AOADC) addresses both RF and optical modeling of a leaky waveguide based optical spatial light modulator (SLM) using electro-optic (E-O) material. The E-O polymer provides improved sensitivity for SLM and achieves a broader bandwidth due to better velocity matching between RF and optical waves.
