The researchers have combined micro-optic and piezo-electric
switches that can achieve both precision and functional rapidity.
The switches are basically micro-lenses that can be moved mechanically
to divert optical beams. Micro-lenses have virtually no optical
faults, which ensure exceptional efficiency in data transmission.
Piezo-electric technology causes a synthetic ceramic component
to expand on applying voltage to offer fast mechanical movement.
The unique switching system can also distribute the incident light
pulse into appropriate channels within a millisecond. The technique
used in this system has further applications in entirely different
fields like miniaturized laser scanners for medical use and laser
material processing for automotive industry and surveillance systems.
