“…Besides optical modulators, other optical devices including optical polarizers, optical filters, optical isolators, optical switchers, optical parametric devices, light‐control‐light device, and even all‐optical signal processing, have been also studied. For example, the researchers developed a broadband polarizer based on graphene to support transverse mode surface wave transmission in visible and near‐infrared bands, as shown in Figure .…”

In recent years, 2D layered materials, including graphene, topological insulators, transition metal dichalcogenides, black phosphorus, MXenes, graphitic carbon nitride, and metal‐organic frameworks, have attracted considerable interest due to their potential applications in the fields of physics, chemistry, biology, and energy. Their rise in the field of nonlinear photonics began around 2009 and has become an important research direction. Here, the synthesis techniques, nonlinear optical properties, integration strategies, and device applications of layered materials are reviewed. In terms of nonlinear optical properties, the focus is on saturable absorption and Kerr nonlinearity. On this basis, their applications in various pulsed lasers, including fiber lasers, solid‐state lasers, waveguide lasers, and related nonlinear optical phenomenon, are summarized. In addition, novel optical devices using layered materials, such as optical modulators, optical polarizers, optical switchers, and even all‐optical device, are also involved. It is believed that the development of 2D layered materials in the field of photonics will continue to deepen, thus laying a good foundation for its practical application.

“…By linearly fitting the data, the maximum wavelength shift efficiency and the maximum modulation efficiency are 24 pm/mW and 0.22 dB/mW, respectively. A large number of previous reports have perfectly demonstrated the huge application of two-dimensional materials in all-optical control fiber devices [11][12][13][14][15][16], and the in-line-MZI device may be more convenient to manufacture.…”

As the oxide-induced disruption from silicon dioxide substrate would greatly decrease the thermal property of graphene, strategies to optimize the thermo-optical response through controlling laser spot size, layer number and covering length of graphene layer are experimentally studied and discussed. An all-optical controlled fiber Mach-Zehnder interferometer with multilayer and monolayer graphene achieved by thermo-optical effects is subsequently proposed to prove the improvements. Graphene layers with 6 mm length were transferred to the middle taper and heated by an external laser. The maximum switching extinction ratio reached 16.2 dB. The response time and modulation efficiency were approximately 620 µs and 0.22 dB mW −1 , respectively. This work suggests an effective way to improve the thermal property of graphene-fiber hybrid structure for all-optical control in fiber based integrated system. Moreover, the cost and complexity of device manufacturing are greatly reduced.

“…A significant mission involves appropriate collection of controlled parts; a controlled part is a set of fixtures or single fixture in luminaire which adjusted by one sign. The purpose in developing a controlled zones and parts is in order to outline zones which receives a constant quantity of natural light at particular duration and hence, reliable light standards requirement [20][21][22][23][24][25].…”

Saving energy and greenhouse gas emissions in commercial buildings become a very serious request of buildings’ designers and engineering crew. The goal behind the current research is to high light and demonstrate the outcome of utilizing advance and intelligent building management system (IBMS) based in utilizing a fuzzy logic controller that allows the usage and the control of natural light (day light). The fuzzy logic controller (FLC) was sat to control the buildings dimming system while utilizing natural light which normally allows to add outdoors illuminance into the inside ones. This control system is significant mean technique that can be used in intelligent buildings commercial buildings, hence energy savings and consequently, greenhouse gas emissions reduction. The proposed control system relies on enumerating the outdoor and the indoor illuminance and allowing some add-on controllers in order to put into effect a photometric computer that capable of comparing and tasking decisions to regulate rooms lighting fixtures. The article also demonstrates energy savings using this technique and then suggest proper markets for using this controlling system whether during the buildings’ design stage, existing commercial buildings.
