“…The complex process represented here just by A (and after by C) need to be with a rate of gigahertz. A complete study is necessary to describe this all-optical process (Robinson et al 2000;Minh et al 2005;Nakamura et al 1994;Hamilton et al 2002). In the proposed modulator, for the first bit (in time) of each pair, will be applied the PPM modulation and PAM for the second.…”

A new optical encryption method using an acousto-optic tunable filter (AOTF) operating simultaneously with pulse position modulation (PPM) and pulse amplitude modulation (PAM) is proposed in this paper. This device operates with ultrashort soliton light pulses (2ps), which are modulated in agreement with the technique of pulse modulation just mentioned. In this way any pulse carries naturally two bits of information but when the encryption proposed here, is applied, each encrypted pulse, carries four bits of information. We have analyzed the sixteen output possible situations, modulating the input pulses polarized in TE and TM modes allowing a variation in the PPM (ε PPM ) and PAM (ε PAM ) parameters for each modulation. We have defined all the possibility pairs of PPM-PAM parameters where the encrypting procedure is possible.

“…In order to alleviate pattern dependency caused by the energy variability of different bit, pulse-position modulation (PPM) is proposed for the control pulse data stream [4,5]. It is a modulation format with constant energy per bit, in which a pulse in the first half of the bit slot represents "0" and a pulse in the second half of the bit slot represents "1" [4].…”

“…It can be easily implemented in OTDM system [4]. Using PPM, significant reduction of the pattem dependency is obtained [5].…”
