Abstract

Poly(methyl methacrylate-co-9-anthrylmethyl methacrylate) (PMMA-AMA) LP-136 with various AMA contents was prepared. The polymer was modified via Diels-Alder (D-A) type "click chemistry". In one approach, the side-chain was grafted stepwise with maleimide-containing chromophore AJL-04 followed with N-phenylmaleimide (PI) to form LP-160. LP-160 was doped with 30 wt % of chromophore AJLS-102 to give electro-optic (EO) core polymer AJ-415. In the other approach, all the pending AMA groups were modified with PI in one step to yield LP-165. Doping 33.7 wt % AJLS-102 in LP-165 gives another core polymer AJ-416. The EO and material properties of both polymers were systematically studied. Via careful selection of bottom and top cladding materials with proper optical and electrical properties, Mach-Zehnder type modulators were fabricated based on both core materials. At the operational wavelength of 1550 nm, modulator with AJ-415 core has half-wave driving voltage (Vπ) of 0.95 V and insertion loss of 19.1 dB, while the best results from modulators with AJ-416 core are 0.75 V of Vπ and 17.1 dB of insertion loss. AJ-416 also has the advantage over AJ-415 for building EO modulator with better processibility and long-term stability.
