Abstract. Tunable dispersion has been implemented in various technology platforms, including fiber gratings, planar waveguides, thin film etalons, and bulk optic technologies. This paper will focus on fiber grating based tunable dispersion compensation, because fiber gratings are at present one of the best developed TDC technologies available. The paper is divided into three parts. In the first part we describe grating based TDC technologies and discuss their advantages and disadvantages. We focus on thermally tuned linearly chirped fiber gratings, as these have to date been the most successful grating technology for 40 Gbit/s. We also compare grating TDCs to two other prominent tunable dispersion technologies: thin film etalons and planar waveguide ring resonators. In the second section we describe the techniques used to fabricate high performance dispersion compensation gratings as well as the theory of the primary defect of fiber grating dispersion compensation: group delay ripple (GDR). In the third section we describe the telecom system related issues for tunable gratings, including characterization of grating performance, tunability requirements and results from actual system trials using tunable FBGs.

“…This characteristic is particularly desirable for some applications such as tunable dispersion compensation since it does not introduce any insertion loss variation. It should be noted that a distributed GT etalon (DGTE) [13] can also realize similar spectra, i.e. a wide band with channelized dispersion.…”

Abstract:We present here a new class of multi-channel Fiber Bragg grating (FBG), which provides the characteristics of channelized dispersion but does so with only a single reflection band. An FBG of this type can provide pure phase control of the spectral waveform of optical pulses without introducing any deleterious insertion-loss-variation. We anticipate that this new class of FBG will find some applications in wavelengthdivision-multiplexing systems.

“…For fibre-optic applications however, it is desirable for GTEs to be made directly in the optical fibre, as it will reduce insertion loss and eliminate alignment issues. The achievement of compact allfibre distributed Gires-Tournois etalons (DGTEs) was reported for the first time in [9], in which the bulk mirrors were replaced by fibre Bragg gratings. After this, several DGTE designs were proposed as dispersion compensation devices, which were based on chirped fibre Bragg gratings, possibly with complex apodization profiles [10,11].…”
