Abstract: We show that rocking filters can be fabricated in photosensitive elliptical-core fibers with 193-nm radiationfrom an excimer laser by the external point-by-point fabrication technique. We find that the writing efficiency at this wavelength is significantly larger than that at 240 nm. Furthermore, the growth dynamics of rocking filters fabricated with these two wavelengths are dissimilar, which may suggest different photosensitive mechanisms.

Abstract: We investigate the effects of UV exposure on the growth of optical fiber rocking filters written in hydrogen-loaded germanosilicate elliptical core fibers. We find that with increasing exposure, the rocking angle (induced birefringence) increases rapidly then begins to decrease, eventually erasing completely. With further exposure, the rocking angle is seen to increase again, reaching values of 3.5°. This corresponds to a photoinduced birefringence almost four times larger than previously recorded in optical fiber rocking filters. Furthermore, we show that at high UV fluences, the direction of rotation of the birefringent axes is opposite to that at low fluences.

Abstract: The refractive index change arising following the UV exposure of a Ge-doped fiber was obtained by measuring the change in the far-field width of the fiber mode in the infrared. Simultaneous measurements showed a gradual decrease in the visible photoluminescence from the fiber which can be directly correlated to the photoinduced index change.
