Optical packet generation apparatus comprising a disk shaped tunable optical filter

摘要

An optical packet generation apparatus, comprising:
a disk shaped optical filter having filter layers of respectively different transmission wavelengths formed on a plurality of fan-shaped regions which are divided at prescribed central angles;a rotation driving mechanism for rotating the disk shaped optical filter at a prescribed speed;a light source for outputting optical beams with at least two wavelengths which coincide with the transmission wavelengths of the filter layers;an optical beam input unit for setting the optical beams from the light source incident onto the disk shaped optical filter as collimated optical beams, substantially perpendicularly to a rotation plane of the disk shaped optical filter; andan optical beam output unit for collecting the collimated optical beams that pass through the disk shaped optical filter and outputting monochromatic optical packets of wavelengths corresponding to the transmission wavelengths of the filter layer in time series, in accordance with rotations of the disk shaped optical filter.
