“…It is worth mentioning that these are general considerations which guarantee that the PPEs associated to this kind optical fiber may describe the propagation of pulses in a large gamut of single-core fibers: classical weakly-guiding fibers, optical gain fibers (amplification can be regarded as negative absorption, as mentioned before), polarization-maintaining fibers, highlynonlinear fibers and photonic crystal fibers. In addition, all-magnetic fibers [34], [35] can also be described by the same PPEs as those of the all-dielectric case (see page 14 of Supplementary Material).…”

The comprehension of pulsed light propagation is of paramount importance in fiber optics. Here, we present a general method to describe the propagation of pulses in any kind of optical fiber, regardless of its fabrication process or constituent materials. As a result, we obtain a rich toolbox for the analysis and synthesis of optical fibers, which allows us to circumvent the resolution of Maxwell's equations by using heavy-computational numerical methods. To illustrate this, we analyze the pulse propagation problem in nonparaxial anisotropic single-core and multi-core fibers that cover a large variety of optical fibers including classical weakly guiding fibers, optical gain fibers, polarization-maintaining fibers, highly nonlinear fibers, and photonic crystal fibers. Moreover, it is shown that our method can be applied to any kind of guided and unguided medium undergoing spatial and temporal perturbations, provided that the distance and temporal width between different consecutive spatial and temporal medium perturbations are respectively higher than the spatial and temporal width of the optical pulses.

“…Basically, PC structure is designed with point defects and line defect to get the photonic band gap (PBG) and these structures could be in the form of 1-Dimensional, 2-Dimensional and 3-Dimensional where, 2-Dimensional PC is highly attractive due to the small size, high operating speed, low loss [2]. Based on 2D PC various devices has been designed such as optical waveguides [4,5], optical sensors [6][7][8], optical filters [9,10], multiplexer/demultiplexer [11][12][13], logic gates [14][15], optical switches [16][17], etc. The optical encoders can be designed with three different techniques as self-collimation [18], nonlinear effect [19][20] and interference effect [21][22][23][24].…”

In the present work, a high-speed optical encoder is proposed based on two-dimensional photonic crystal ring resonator (2D-PCRR) using coupled mode theory and resonance effect. Square shaped ring resonator, couplings rods and several waveguides have been utilized in the proposed structure. Silicon rods in air structure has been designed with rod radius of 0.1a and lattice constant 0.540 nm. The photonic band gap is being calculated using plane wave expansion method and finite-difference-time-domain method to analyze the performance characteristics of optical encoder like: transmission spectra, electric field view, contrast ratio, delay time, response time etc. The operating wavelength of structure is 1550 nm, to perform encoder operation where only one input port is activated at a time while other input ports are inactivated and accordingly equivalent binary encoded signal is produced at output ports. The proposed encoder is designed with fast response time 222.76 fs, high data rate of 4.48 Tbps and ultra-compact size of 140.84µm2. Hence the proposed device is suitable for high-speed optical computation, photonic integrated devices and high speed optical integrated circuits.
