“…We have pioneered microwave-assisted synthesis as applied to the production of organic electroactive materials and have been a leader in developing new lattice hardening chemistries, particularly Diels-Alder/Retro-Diels-Alder cycloaddition reactions, which have yielded organic electro-optic materials with glass transition temperatures exceeding 200°C [11,34,38,47]. Our laboratory has pioneered the fabrication of complex device structures, such as coupled multi-ring microresonators by soft and nanoimprint lithography and we have been actively involved in the fabrication of conformal and flexible devices by lift-off techniques.…”

“…In designing our template, we were motivated by the need to modify chromophores for a broad range of hybrid material device applications. [7][8][9][10] The template can be generalized to different core and pendant structures. Further control can be achieved by systematic variation of the shape of the core and the total molecular weight of the macromolecular unit.…”

A new molecular template permits nano-engineering of soft matter materials to optimize optical and optoelectronic properties.Organic materials offer exceptional electro-optic activity, bandwidth, and processability. They are also low-cost, flexible, and compatible with diverse materials. Hybrid devices (that combine organic materials with silicon technologies) offer chip-scale integration of electronics and photonics, which could support applications in telecommunications, high-performance computing, radio-frequency (RF) photonics, and sensing technologies. Such integration requires organic materials that are adaptable to a range of processing options and conditions. They also need to have optimal optical and optoelectronic properties, which depend on order and lattice dimensionality. It has proven very

“…A sea change in electro-optic technology (and ultimately, optical rectification technology) has occurred with (1) the advent of the subwavelength technologies of silicon photonics and plasmonics ,− and with (2) theory-guided improvement of the r 33 values and other relevant properties of OEO materials. ,, Silicon photonics and plasmonics have facilitated a dramatic reduction in device dimensions. Plasmonic–organic hybrid (POH) device lengths can be reduced to less than 10 μm and electrode spacings to less than 50 nm (nm).…”

The performance of electro-optic devices based on organic second order NLO materials has been improved by orders of magnitude through theory-guided improvement in the electrooptic activity and other relevant properties of organic materials and by field compression of radio frequency (RF) and optical fields associated with the transition from microscale/mesoscale devices to silicon−organic hybrid (SOH) and plasmonic−organic hybrid (POH) devices with nanoscopic dimensions. This paradigm shift in organic electro-optic R&D has led to many performance improvements, including record performance for voltage-length performance of less than 50 V-μm, energy consumption of less than 70 attojoules/bit, bandwidths of greater than 500 gigahertz (GHz), and device footprints of less than 20 μm 2 . Another consequence of improving electro-optic performance is the corresponding improvement of the converse second order nonlinear optical property of optical rectification (transparent photodetection). Theory has permitted identification of optimum optical nonlinearity/transparency values and dipole moments for newly developed chromophores, which have led, in turn, to state-of-the-art materials and device performance.
