Abstract

A surface nanoscale axial photonic (SNAP) device in the form of an optical bottle resonator is configured to exhibit a semi-parabolic profile (in terms of a change in radius along the longitudinal direction of the fiber). It has been found that this semi-parabolic profile provides the ability to create the dispersionless delay of optical pulses, where “dispersionless” in this case is considered to mean that the pulse retains its same shape with minimal distortions as it passes back and forth within the bottle resonator (i.e., minimal pulse-broadening). Delays on the order of several nanoseconds have been created within these semi-parabolic-shaped SNAP bottle resonators of about 3 mm in length (as compared with prior art microresonator devices' ability to create delays no greater that 1 ns, at best).
