“…Optical bistability (OB) is a fascinating nonlinear optical phenomenon that exhibits a clear hysteresis loop relationship between the output and input light intensity, characterized by two corresponding output intensities for a given input intensity [1]. The OB phenomenon has excellent nonlinear optical properties and has been widely used in various micro-nano optoelectronic devices in recent years, such as biosensors [2], all-optical switches [3], optical memory [4], optical logic devices [5], optical transistors [6], etc. With the increasing demand for micro-nano optoelectronic devices and the maturity of micro-nano fabrication technology, more and more researchers are focusing on the design of micro-nano optically bistable devices.…”

In this paper, we theoretically investigated the low-threshold and controllable optical bistability (OB) of a graphene-based Otto configuration with a nonlinear three-dimensional Dirac semimetal (3D DSM) as the substrate. The combined effect of the excitation of surface plasmon polaritons (SPPs) in graphene and the very high third-order nonlinear conductivity of the 3D DSM enabled this scheme to achieve a relatively low optical bistability threshold. At the same time, this simple multilayer structure showed the tunability of OB due to the fact that the reflectance could be modulated by regulating the Fermi energy of the 3D DSM. Furthermore, we also found that the OB hysteresis curve was closely related to the relaxation time of the 3D DSM and the thickness of the air layer. We believe that this multilayer configuration could provide a reference idea for devising a bistable device.

“…As mentioned above, in most literature, each all‐optical signal processing function is demonstrated separately. It is necessary for multi‐functional optical processing units to perform multiple optical signal processing functions simultaneously in flexible optical networks, and there have been a few reports 21–25 . Multi‐functional optical processing units have better integration and can enhance the flexibility and scalability of the optical network, and thus attracted much attention from researchers.…”

“…In Reference 24, WDM multicast, wavelength conversion, modulation format conversion, and hybrid modulation format exclusive‐OR, based on FWM in highly nonlinear fiber, are realized simultaneously by simulation. In Reference 25, all‐optical switching and multiple logic gates are experimentally demonstrated using hybrid square‐rectangular lasers.…”

In this article, a multifunctional optical processing unit for differential eight phase‐shift‐keying (D8PSK) and differential quadrature phase‐shift‐keying (DQPSK) based on four‐wave mixing (FWM) effects in semiconductor optical amplifier (SOA) is proposed. All‐optical wavelength conversion, D8PSK‐to‐DQPSK format conversion and signal encryption of 10‐Gbaud DQPSK and D8PSK optical signals are achieved simultaneously by simulation. Detailed theoretical analysis and simulation results are conducted to verify the feasibility of the scheme. The Q factor of the electrical signals and the bit error rate recovered from wavelength and format converted components are approximated to be around 6, and 10−9, which indicates the feasibility of the scheme. For the encrypted signal, the FWM effect of another SOA is utilized to decrypt the encrypted signal, and the encryption function of 10‐Gbaud DQPSK and D8PSK optical signals is also verified.
