Abstract
Techniques for monitoring optical waveguides are disclosed.
Claims48
A method for monitoring the quality of a photonic crystal fiber, the method comprising:
- directing test light toward a side of a photonic crystal fiber;
- detecting measurement light emerging from the photonic crystal fiber in response to the test light;
- and
- monitoring the quality of the photonic crystal fiber based on the measurement light.

A method for monitoring the quality of an optical waveguide, the method comprising:
- directing broadband test light to a side of an optical waveguide;
- detecting measurement light reflected from the optical waveguide in response to the test light;
- determining the measurement light intensity at a plurality of wavelengths;
- and
- monitoring the quality of the optical waveguide based on a measurement spectrum of the measurement light.
2 more elements
An apparatus for monitoring a photonic crystal fiber, the apparatus comprising:
- a mount for supporting the photonic crystal fiber;
- an illumination system which during operation directs test light to a side of the photonic crystal fiber;
- and
- a detection system which during operation detects measurement light emerging from the photonic crystal fiber in response to the test light.
