Abstract
A photonic crystal waveguide for conveying light with an input end and an output end to supply for an electromagnetic spectrometer includes: an input end having a convex envelope of a cross-section of the waveguide at the input end, which envelope defines a circular shape or a shape of a regular polygon with n1 corners, wherein n1 is a natural number bigger than 3; an output end having a cross-section that defines a slit shape; and a plurality of photonic crystal fibers, wherein an arrangement of the plurality of photonic crystal fibers defines the cross-sections at the input and output ends.
Claims20
A photonic crystal waveguide for guiding light configured for an electromagnetic spectrometer, the waveguide comprising:
- a plurality of fibers, each configured to convey light from an input end to an output end thereof, wherein a first convex envelope of a cross-section of the waveguide at the input end defines a first shape, and wherein a second convex envelope of a cross-section of the waveguide at the output end defines a slit shape,
- wherein each fiber is a photonic crystal fiber comprising a support structure and uniformly arranged channels within the support structure.
