Deposition of semiconductors and metals from chemical precursors
onto planar substrates is a well-developed science and technology
for microelectronics. Optical fibers are an established platform
for both communications technology and fundamental research
in photonics. Here, we describe a hybrid technology that integrates
key aspects of both engineering disciplines, demonstrating the
fabrication of tubes, solid nanowires, coaxial heterojunctions,
and longitudinally patterned structures composed of metals,
single-crystal semiconductors, and polycrystalline elemental
or compound semiconductors within microstructured silica optical
fibers. Because the optical fibers are constructed and the functional
materials are chemically deposited in distinct and independent
steps, the full design flexibilities of both platforms can now
be exploited simultaneously for fiber-integrated optoelectronic
materials and devices.
