WebJul 2, 2004 · Chiral fiber gratings naturally have the sinusoidal profile of the refractive index, which is desirable for producing harmonics-free fiber grat ings. It is a challenge to achieve such a profile with a conventional approach ( 9 ). We fabricated two types of right-handed chiral fiber gratings ( Fig. 2 ). These were a 55-mm-long CLPG with a pitch ...
