Research Topics


Electro-optic modulators and switches are an integral part of many photonic systems. This project will develop an electro-optic fiber that will be used as a basic building block for in-line electro-optic devices. Electro-optic fibers will overcome many of the drawbacks associated with conventional planar designs. They will have lower overall optical loses for the final packaged device and greatly reducing end unit cost. Pigtailing will be reduced to fiber splicing (a well-known, routine commercial operation costing well under $1 per splice compared to $100's for pigtailing chips). Completion of Phase I research will set the foundation to develop fiber optic in-line sagnac modulators and other devices in Phase II research. Using electro-optic fibers, devices may be fabricated directly in the fiber, integrated by fusing fibers or using multiple cores, or used in hybrid technologies such as combining electro-optic fibers with other active fiber devices such as Erbium Doped Fiber Amplifiers.
