Chemical structure of AJL8 chromophore.
Fabrication of the PDMS stamp (a)–(c) and replication (d)–(f). A master MZI device (a) is patterned by photolithography of SU-8. PDMS is poured on the master device (b), cured, peeled, and diced (c). A drop of electro-optic core solution is placed on the appropriate substrate (d). The PDMS stamp is depressed (e) until the core polymer is cured. The stamp is peeled to reveal the high-fidelity replicated device (f).
Cross-sectional view of the electro-optic waveguide structure. The core electro-optic polymer is AJL8/APC and the upper and lower cladding materials are low refractive index epoxy WR-513.
Measured modulator output as a function of applied voltage.
