“…Controlling the group velocity of light has attracted more and more attention due to its potential application in data synchronization, tunable optical buffer in optical communication [1], optical information processing and optical switching [2]. To date, varies techniques of controlling the group velocity of a pulse have been studied, such as electromagnetic induced transparency (EIT) [3,4], coherent population oscillation (CPO) [5], stimulated Raman scattering (SRS) [6], and stimulated Brillouin scattering (SBS) [7].…”

In this article, we experimentally demonstrate a new way of controlling the group velocity of an optical pulse by using a combination of spectral hole burning, slow light effect and linear Stark effect in a rare-earth-ion-doped crystal. The group velocity can be changed continuously by a factor of 20 without significant pulse distortion or absorption of the pulse energy. With a similar technique, an optical pulse can also be compressed in time. Theoretical simulations were developed to simulate the group velocity control and the pulse compression processes. The group velocity as well as the pulse reshaping are solely controlled by external voltages which makes it promising in quantum information and quantum communication processes. It is also proposed that the group velocity can be changed even more in an Er doped crystal while at the same time having a transmission band matching the telecommunication wavelength.

“…In particular the AND gate is indispensable for achieving this goal as it is involved in the accomplishment of numerous tasks in the optical domain both in fundamental and system-oriented level, such as buffering [2], address comparison [3], add-drop multiplexing [4], packet clock and data recovery [5], packet header and payload separation [6], binary pattern recognition [7], binary counting [8], analog-to-digital conversion [9], digital encoding and comparison [10], data regeneration [11], waveform sampling [12], half addition [13], multiplication [14], construction of other logic gates [15] and of combinational logic circuits [16]. Given its important, multi-lateral role the AND gate has attracted intense research interest and among the technological options that exist for its implementation those that exploit a semiconductor optical amplifier (SOA) are well established [17].…”

Abstract-The feasibility of realizing an all-optical AND gate for 320 Gb/s return-to-zero data by incorporating quantum-dot semiconductor optical amplifiers (QD-SOAs) in a Mach-Zehnder interferometer (MZI) is theoretically investigated and demonstrated. The proposed scheme employs the QD-SOA-based MZI in a configuration where the QD-SOA in one MZI arm is subject to the first data sequence, the QD-SOA in the other MZI arm receives no such input but is constantly held in the small signal gain regime, and the second data stream is inserted from the common MZI port acting as enabling or disabling signal. Compared to other approaches adopted for the same purpose this implementation is more general, direct, flexible and affordable as only one strong data signal is required to control switching. By conducting numerical simulation the impact of the critical parameters on the Q-factor is thoroughly assessed. The obtained results are interpreted with the help of a complete characterization of the QD-SOA response to an ultrafast data pulse stream. This allows to specify the requirements that the critical parameters must satisfy to achieve acceptable performance. The extracted design rules are technologically realistic and ensure AND operation both with logical correctness and high quality. The outcome of the numerical treatment extends the range of Boolean functions executed with the QD-SOA-MZI module at sub-Tb/s data rates.

“…TTD can be used to effectively steer an RF beam in different directions in a phased array antenna system and to avoid the squinting problem [4]. In an all-optical network, tunable delays enable a myriad of functionalities including synchronization [5], time-division multiplexing [6] and contention resolution in an optical buffer [1,3]. In a dispersive medium, group velocity of light (to the first-order approximation) can be expressed as v f =-(1) " g i \ dn where n = n\co) + co is the group index, n(co) is the frequency dependant refractive index of the dco medium.…”
