“…Using this all-fiberized polarization insensitive linear technique, we have successfully demonstrated the application of pulse reshaping for optical regeneration/retiming [2], [3], demultiplexing [4], and optimal pulse compression [5]. In this letter, we demonstrate a simple, cost-effective, alloptical wavelength converter based on self-phase modulation (SPM) and offset filtering which is particularly suited for applications in which the required wavelength shift is modest [6].…”

Abstract-We experimentally demonstrate the generation of picosecond triangular optical pulses using a superstructured fiber Bragg grating and show experimentally that use of this pulse shape can provide a three-fold improvement in conversion efficiency relative to the use of Gaussian pulses with similar pulsewidths when used in a wavelength conversion scheme based on self-phase modulation and subsequent offset filtering.Index Terms-Fiber Bragg grating, highly nonlinear fiber (HNLF), optical Kerr effect, optical pulse shaping, self-phase modulation (SPM).

“…The correlation-based technique of optical code (OC) label recognition has advantages compared to the above techniques, such as not requiring clock extraction to read label information and also offering low latency [14]. This technique has already been implemented by using super structured fiber Bragg gratings (SSFBGs) or a planer lightwave circuit (PLC) [15,16].…”

A novel architecture of optical code (OC) label generation and recognition for optical packet switching (OPS) by using super structured fiber Bragg grating (SSFBG) is proposed. The OC label is generated and recognized by a label generator and recognizer, respectively. The label generator is composed of N encoders in parallel, and it can generate 2N kinds of serial optical code labels (SOCLs) for indicating 2N network routing information. The label recognizer can decode SOCLs by N decoders in parallel and provides label information to the switching control unit so that clock information is not required during the decoding process. In the switch nodes, handling of the high-speed information payload stream and the recognition of the OC label are performed in the optical domain, while processing of the routing information remains in the electrical domain. This approach could be a promising solution for an OPS network with high capacity, good quality of service (QoS), multi-service function and high security. In this experiment, we demonstrate 40 Gbps 256 label optical packet switching that employs clockless SOCL processing.

“…In this paper, we demonstrate timing jitter reduction in an optical time division multiplexing (OTDM) system operating at data rates up to 160 Gbit/s by linearly reshaping RZ data pulses in a polarization insensitive SSFBG into longer rectangular (flat-top) pulses (~5ps) and then switching these pulses in a nonlinear Kerr switch with a synchronous optical clock signal [3,[9][10], while maintaining the original wavelength. SSFBG technology offers a ready route to the production of optical filters with very precisely controlled frequency and phase profiles of almost arbitrary complexity in a single continuous grating structure and which can therefore be used to manipulate the properties of incident optical signals.…”

Abstract-This paper demonstrates a retiming system operating at rates of 40 and 160 Gbit/s, which incorporates a superstructured fiber Bragg grating (SSFBG) as a pulse shaping element. The original data pulses are shaped into flattopped (rectangular) pulses to avoid conversion of their timing jitter into pulse amplitude noise at the output of a nonlinear fiber-based Kerr switch. Thus retiming is performed in a single step avoiding wavelength conversion. The benefits of using shaped rather than conventional pulse forms in terms of timing jitter reduction are confirmed by bit-error rate (BER) measurements.
