Contribution

It introduces a novel locking scheme and phase modulation technique to suppress acoustic interactions, enabling large-scale, long-duration optical data storage in a fiber ring resonator.

Findings

Stored 4536 bits at 10 Gb/s for 1 minute

Implemented a new locking scheme for multiple solitons

Suppressed acoustic interactions via phase modulation

Abstract

We demonstrate the operation of an all-optical buffer based on temporal cavity solitons stored in a nonlinear passive fiber ring resonator. Unwanted acoustic interactions between neighboring solitons are suppressed by modulating the phase of the external laser driving the cavity. A new locking scheme is presented that allows the buffer to operate with an arbitrarily large number of cavity solitons in the loop. Experimentally, we are able to demonstrate the storage of 4536 bits of data, written all-optically into the fiber ring at 10 Gb/s, for 1 minute.
