“…When the input logic is high, it prevents the coupling of the reference input into the ring resonator [21]. The resonance wavelength of the ring resonator is shifted due to Kerr nonlinear effect [21,22] and the reference input is transmitted to the output port. When optical signals of the high intensities propagate through the ring resonator, the effective refractive index of the structure varies due to Kerr nonlinearity; thereby changing the resonant wavelength of the structure [21,22].…”

The future of telecommunication and optical communication networks is extremely focused on the design and development of photonic integrated circuits (PICs). Photonic crystals play the foremost role in realizing all optical integrated circuits. Every single optical component required to be integrated in PICs can be outlined based on the requirement of the application and can be obtained with the photonic band gap property of photonic crystals. Numerous works on different optical components has been done using photonic crystals. Among which, optical digital-to-analog converters (DACs) need to be explored and attended to incorporate into PICs. In this paper, photonic crystal-based 1-bit and 2-bit DACs, suitable for the photonic integrated circuits application, are proposed. Photonic crystal ring resonators and waveguides were integrated into the reported structures. The Kerr effect of the ring resonators has been utilized to provide an average error of 4.8477% for a 2-bit optical DAC. The devised structure provides an insertion loss of −5.5596 dB, with an overall dimension of 358 µm 2 . The DAC structures were simulated using finite difference time domain and plane wave expansion methods.

“…Thus, O1 yields the result of an AND operation and O2 the result of a digital XOR. The intensity value 2 output of O1 (AND) must be normalized to yield a digital output [13,14]. [13] illustrates the use of the Bragg grating as a hardlimiter in the construction of OR gate.…”

The orthogonal variables spreading factor (OVSF) provides variables data rates to flexible support many applications with different bandwidth. This paper presents an optical OVSF code generator using all optical gates and a set of all optical flip-flops based on two coupled polarization switches (PSWs). The optical OVSF code generator helps to use the OVSF code technique in optical communications. The general objective is to make the OVSF code tree suitable to support a lot of users in the optical communication links. The overall design and the results are discussed through the realization and the computing numerical simulation to confirm its operation and feasibility. The proposed scheme has been theoretically demonstrated for a spreading factor of 4 and 8.
