Paper Abstract

We demonstrate through numerical simulations that a fiber Bragg grating operated in transmission can support much slower light than previously anticipated. This is accomplished by increasing the grating's index modulation, reducing its loss, optimizing its length, and apodizing its index profile. With current fiber Bragg grating loss and index modulation, we predict that group velocities lower than c/1000 are attainable. We validate this concept with a record measured group index of 130 in a strong apodized grating (index modulation of ~1.1 10-3) with a nearly optimized length of 1.2 cm and an inferred loss coefficient of 1 m-1.
