Abstract
A leaky waveguide includes a waveguide configured to propagate light; a defect structure provided on a portion of the waveguide and configured to cause the light propagating in the waveguide to leak outside of the waveguide; and a plurality of detectors provided at predetermined positions adjacent to the defect structure and configured to detect the light leaking from the defect structure. Accordingly, a spectroscope including the leaky waveguide may have a reduced size.
Claims16
A leaky waveguide comprising:
- a waveguide configured to propagate light;
- a defect structure provided on a portion of the waveguide and configured to cause the light propagating in the waveguide to leak outside of the waveguide;
- and
- a plurality of detectors provided at predetermined positions adjacent to the defect structure and configured to detect the light leaking from the defect structure,
- wherein the predetermined positions are positions at which the light leaking from the defect structure are combined by interference.

A spectroscope comprising:
- a waveguide configured to propagate light;
- a defect structure provided on a portion of the waveguide and configured to cause the light propagating in the waveguide to leak outside of the waveguide;
- a plurality of detectors provided at predetermined positions adjacent to the defect structure and configured to detect the light leaking from the defect structure;
- and
- a calculator configured to perform a calculation to reconstruct a wavelength spectrum of the light incident on the waveguide based on amounts of the light leaking from the defect structure detected by the plurality of detectors,
- wherein the predetermined positions are positions at which the light leaking from the defect structure are combined by interference.
