Multilevel registered polymeric Mach–Zehnder intensity modulator array

Abstract

Described here is the first known demonstration of a registered two level guided wave polymeric electro-optic Mach–Zehnder intensity modulator array. The device consists of two complete vertically stacked levels. Both levels were independently poled and operated. There was no measurable optical or electrical cross talk due to a high resistivity thermoset polymer buffers layer employed. Fabrication and performance of the device is discussed.

Nonlinear optical polymer electrets current practice

“…Exploiting the relatively easy processability, advanced multilevel devices that hardly can be designed with inorganic materials have been demonstrated, such as a vertically stacked directional coupler switch by Hikita and coworkers at NTT [194] and a multilevel Mach-Zehnder intensity modulator array by Tumolillo and Ashley [195]. Figure 23 shows the cross section of the multilevel Mach-Zehnder modulator array, consisting of ten distinct spin-coated layers.…”

Synthesis of new aromatic perfluorovinyl ether monomers containing phosphonic acid functionality

“…Authors reported the synthesis of poly(aryl vinyl ether) based on a two steps synthetic route (Scheme 1) [9]: the first one concerned a fluoroalkylation with BrCF 2 CF 2 Br while the second one dealt with a zinc mediated elimination. [8,15].…”

Synthesis, optical nonlinearity and fabrication of a waveguide device on urethane–urea copolymers

“…Most EO devices are waveguidetype structures because an electric field can be applied to the waveguides effectively and the waveguide structures could play important role in optically integrated circuits. Various kinds of EO device have been investigated using EO polymer and have been demonstrated to show high bandwidth modulation using a traveling-wave electrode [7,8] and vertically integrated modulator [9,10].…”
