摘　　要：An optical scrambler using a whispering-gallery-mode[WGM]micro-bottle cavity to scramble a complex optical signal to generate an uncorrelated output is proposed.We experimentally demonstrated this micro-cavity scrambler by using chaotic laser light as the incident signal and studied the influence of the coupling state.Experiments achieved full scrambling with a low cross correlation of 0.028 between the output and the input.Results indicate that the scrambling effect originates from the interference among numerous WGMs in the bottle cavity.It is believed that the micro-bottle cavity with an efficient scrambling function can become a promising candidate for encryption.
