“…e photonic crystal fiber and data used for FOPA design in this paper are similar to the data used by Taghizadeh et al in [13]. It will be shown that the four-sideband theory allows the prediction of gain shrinkage around the pumps making it appropriate for use in the designing of FOPA [7].…”

In this paper, we seek to compare the two design theories for fiber optical parametric amplifier through simulation. The two-sideband method (standard method) has been the most widely used method in fiber optical parametric amplifier design, but it does not predict the gain shrinkage around the pumps. This technique does not consider the gain shrinking dynamics around the pump(s). The four-sideband analytical technique is an alternative technique for fiber optical parametric amplifier design, and it allows for a simplified investigation of the gain shrinking dynamics around the pump(s) due to the interaction of the various arising high-order idlers within the vicinity of the pump waves. The undertaking in this paper is to present a dual-pump fiber amplifier based on the highly nonlinear fiber and another one based on the photonic crystal fiber and ascertain if gain shrinking affects both FOPAs.

“…In recent times, FOPAs based on FWM and six-wave mixing with bandwidth up to 600 nm and 150 nm, respectively, have been shown [7]. Using the FWM theory, the gain bandwidth and the uniformity of parametric amplifiers can be increased significantly especially by using dual pumps.…”

“…Other proposed structures including fiber optical parametric amplifiers have reached broadband (over 1530–1600 nm) and high (more than 56 dB) optical gain values exploiting photonic crystal fibers. Nonetheless, these require the exploited fiber length to be more than 25 m and strictly depend on center pump wavelength in order to tune their optical gain bandwidth 36 .…”

In this work, the optical gain engineering of an ultra-broadband InGaAs/AlAs solution-processed quantum dot (QD) semiconductor optical amplifier using superimposed quantum structure is investigated. The basic unit in the proposed structure (QDs) is designed and fabricated using solution-processed methods with considerable cost-effectiveness, fabrication ease, and QDs size tunability up to various limits (0.1 nm up to the desired values), considering suitable synthesis methods. Increasing the number of QDs, the device can span more than 1.02 μm (O, C, S, and L bands) using only one type of material for all QDs, and is not restricted to this limit in case of using more QD groups. Also, it can manipulate the optical gain peak value, spectral coverage, and resonant energy for customized optical windows, among which 1.31 μm and 1.55 μm are simulated as widely-applicable cases for model validation. This makes the device a prominent candidate for ultra-wide-bandwidth and also customized-gain applications in general. Variation impact of homogeneous and inhomogeneous broadenings, injection current and number of QD groups on optical gain are explained in detail. Besides proposing a design procedure for implementation of an ultra-broadband optical gain using superimposed QDs in solution-processed technology, the proposed gain engineering idea using this technology provides practically infinite bandwidth and an easy way to realize. By introducing this idea, one more step is actually taken to approach the effectiveness of solution process technology.
