Analysis and Demonstration of Mach–Zehnder Polymer Modulators Using In-Plane Coplanar Waveguide Structure

RF photonic downconversion of vector modulated signals based on a millimeter-wave coupled electrooptic nonlinear polymer phase-modulator

“…Put another way, the enhancement factor affects the carrier-to-sideband ratio while the optical insertion loss preserves the CSR but lowers the power of both the carrier and the sidebands. This is similar to the well-known trade-off between V π in EOMs and optical loss due to metallic electrodes [16]. In the experimental setup, it is important that the firstorder sideband power be sufficient to meet the minimum power threshold of the optical amplifier.…”

High speed electro-optic polymer phase modulator using an in-plane slotline RF waveguide

“…For a polymeric EO modulator, the MZ intensity modulator using inplane CPW type has been proposed in order to enhance poling efficiency, overlap factor, and half wave voltage (V π ). Because the top and bottom cladding layers, necessary for optical guiding, experience part of the voltage drop across the microstrip line waveguide structure thereby reducing the voltage across the core layer, the in-plane CPW showed better performance than a conventional microstrip line structure 6,7 . For phase modulators, two possible RF structures are possible as shown in Fig.…”

Demonstration of a high-speed switch with coplanar waveguide electrodes based on electro-optic polymer-clad waveguides

“…[1][2][3][4][5][6] Optical switches are important elements in many applications, such as optical cross connect (OXC), optical add-drop multiplexing (OADM), and optical true time delay (TTD). 10 Research is continuing to improve the performance of MZI devices such as driving voltage, bandwidth, response speed, and optical and microwave loss by means of new materials and novel structures. 10 Research is continuing to improve the performance of MZI devices such as driving voltage, bandwidth, response speed, and optical and microwave loss by means of new materials and novel structures.…”

“…[7][8][9] Optical Mach-Zehnder interferometer (MZI) modulators and switches based on the EO effect have served as one of the fundamental and important elements in optical ber data transmission system. 10 Research is continuing to improve the performance of MZI devices such as driving voltage, bandwidth, response speed, and optical and microwave loss by means of new materials and novel structures. [11][12][13] The parameters of EO MZI devices are determined by both the properties of EO materials and the electrode structures.…”

“…However for the typical optical MZI switch electrode spacing and width, the CPW electrodes have the advantage of lower microwave signal loss, which is a determining factor for the 3 dB bandwidth. 10 In fact, the EO overlap factor is also relevant with the waveguide structure. In this paper, we will present an easy-tofabricate approach to increasing the overlap in the CPW case by fabricating the EO polymer-clad waveguides on silica substrate.…”
