The resulting module exhibits robust performance over temperature, frequency and bias and is telco-qualifiable.

The platform consists of a material system that has an index contrast that is adjustable from 0 to 25% and which is processed using conventional CMOS tools. The platform allows one to four orders of magnitude reduction in the size of optical components compared with conventional planar technologies. As an example, meter long path lengths occupy coils that are millimeters in diameter. Microwave photonic building blocks that are enabled include large bit count programmable delay lines for beam steering and shaping that fit in less than a square centimeter and which have delays controllable from 5 fsec to 10 nsec. Also enabled are arrays of high order tunable filters, a hundred micrometers in size, having linewidths ranging from tens of MHz to tens of GHz. These filters can be tuned over several hundred GHz, and when placed in Vernier architectures can be tuned across the C band (5 THz). An optical chip typically consists of dozens of optical elements. Each element is placed in its own micro-control loop that consists of a thin film heater for thermo-optic control and a thermistor for electronic feedback. The micro-control loops impart intelligence to the optical chip.","PeriodicalId":137956,"journal":{"name":"2004 IEEE International Topical Meeting on Microwave Photonics (IEEE Cat.

Dalton","doi":"10.1109/MWP.2004.1396819","DOIUrl":"https://doi.org/10.1109/MWP.2004.1396819","url":null,"abstract":"Quantum and statistical mechanical calculations have been used to guide the development of a new generation of electro-optic materials exhibiting electro-optic coefficients in excess of 200 pm/V (seven times that of lithium niobate) and femtosecond response times (leading to device 3 dB bandwidths in excess of 200 GHz). These advances have been based on (1) improvement in molecular first hyperpolarizability by design of novel chromophores and (2) control of intermolecular electrostatic interactions by nanoscopic engineering to realize improved noncentrosymmetric order. Theoretical calculations have also defined the limits of electro-optic activity that can be achieved with a variety of material development approaches including exploitation of dendritic and dendronized polymer structures and self-assembly, sequential synthesis fabrication. A clear paradigm for the short term improvement of electro-optic activity to values a factor of ten greater than lithium niobate will be given as will a longer term development program for improvement to values thirty (or more) times greater than lithium niobate. New nanoscopically-engineered electro-optic materials also exhibit dramatically improved optical loss, thermal stability, and photochemical stability as well as improved control of solubility and processability. Structure/function studies have clarified the variation of photostability with chromophore structure, macromolecular structure including lattice hardness, and the presence of chemical and physical quenchers of singlet oxygen. It is clear that materials surpassing Telcordia standards can be prepared. Insights into the exceptional stability of organic electro-optic materials to space radiation will also be presented. Finally, organic electro-optic materials have been used to fabricate a variety of novel stripline, cascaded prism (and superprism) and ring microresonator (and photonic crystal) devices including devices that are conformal and flexible. An overview of the unique performance properties of such devices will be presented for applications such as active chip-scale wavelength division multiplexing and space-based antennae applications.","PeriodicalId":137956,"journal":{"name":"2004 IEEE International Topical Meeting on Microwave Photonics (IEEE Cat.
