“…In [3,4], the asymmetric parallel-coupled lines were implemented to excite a notched band. The meander line slot was adopted to produce the narrow rejection band in [5]. A split ring resonator (SRR) or complementary SRR (CSRR) unit can also be designed to obtain the required stop band [6].…”

“…In this case, the attenuation of light propagates within the system (i.e., wave guided) used is 0.5 dBmm À1 . After light is input into the system, the Gaussian pulse is chopped (sliced) into a smaller signal spreading over the spectrum due to the nonlinear effects [5], which is shown in Figure 2(a). The large bandwidth signal is generated within the first ring device.…”

This paper proposes a technique of quantum code generation using optical tweezers. This technique uses a microring resonator made of nonlinear fibre optics to generate the desired results, which are applicable to Internet security and quantum network cryptography. A modified add/drop interferometer system called PANDA is proposed, which consists of a centred ring resonator connected to smaller ring resonators on the left side. To form the multifunction operations of the PANDA system—for instance, to control, tune and amplify—an additional Gaussian pulse is introduced into the add port of the system. The optical tweezers generated by the dark soliton propagating inside the PANDA ring resonator system are in the form of potential wells. Potential well output can be connected to the quantum signal processing system, which consists of a transmitter and a receiver. The transmitter is used to generate high‐capacity quantum codes within the system, whereas the receiver detects encoded signals known as quantum bits. Therefore, an entangled photon pair can be generated and propagated via an optical communication link such as a time division multiple access system. Here, narrower potential wells with a full‐width half‐maximum of 3.58 and 9.57 nm are generated at the through and drop ports of the PANDA ring resonator system, respectively, where the amplification of the signals occurs during propagation inside the system.

“…They have also shown that the different time slot entangled photons can be formed randomly and can be used to select two different frequency bands for up–down link converters within a single system. Yupapin et al [5] have proposed a new technique for QKD that can be used to make the communication transmission security and implemented with a small device such as mobile telephone hand set. This technique has proposed the Kerr nonlinear type of light in the microring resonator to generate the superposition of the chaotic signal via a four‐wave mixing type that introduces the second‐harmonic pulse.…”
