Page 5 - Fiber Bragg Gratings

The cover picture shows the near-field photographs of radiation mode patterns of
several low-order counterpropagating modes (LP 0n). These are excited by the forward
propagating core mode in a 6-mm-long, side-tap grating with a 2° blaze angle, written
into the core of a single mode fiber. Artwork by Arjun Kashyap.
