Multimaterial Photonic Bandgap Fibers
Photonic bandgap fibers guide light by reflection on an omnidirectional dielectric mirror. This structure allows us to overcome limitations of conventional fiber optics and enables light to be controlled in ways not previously possible.
Electronic and Optoelectronic Fiber Devices
By combining metals, semiconductors, and insulators in well-defined geometries and prescribed sizes, we realize functional fiber devices.
Microfluidic Fiber Devices
We engineer novel light emitting devices by merging fluidics with photonic bandgap fibers.
To achieve an active fiber whose properties can be electrically controlled at high frequencies, we introduce a ferroelectric polymer layer. The resulting piezoelectric fiber is an acoustic transducer from kHz to MHz frequencies.
