“…• c Exact value not reported in [20] so percentage improvement is (approximately) inferred from a graph presented in [20]. Comparison made at bias current value corresponding to the best case performance of the best performing ASM mount + drive combination and is compared against the STF mount + drive at the same bias and for the same drive (step was best performing in the reported metrics).…”

“…The results therefore are complementary to those presented in this work, which improves the SOA output purely by means of driving signal optimisation. It is speculated here that the optimisation of the SOA's driving signal by the methods presented in this work combined with the optimisation of its microwave mounting could achieve greater improvements in its output than seen in either [20] or this work.…”

“…Similarly, [20] explores the optimisation of an SOA by means of both modification of the driving signal and optimisation of the SOA's microwave mounting. A best case of 33% reduction in guard time is accomplished with an improved microwave mounting architecture and a step driving signal, where various MISIC and PISIC driving signals were also tested.…”

Novel approaches to switching ultra-fast semiconductor optical amplifiers using artificial intelligence algorithms (particle swarm optimisation, ant colony optimisation, and a genetic algorithm) are developed and applied both in simulation and experiment. Effective off-on switching (settling) times of 542 ps are demonstrated with just 4.8% overshoot, achieving an order of magnitude improvement over previous attempts described in the literature and standard dampening techniques from control theory.

“…The high-speed transmission of 160 Gb speed was achieved using optical time-division multiplexing based on MZI switching [18]. The electro-optic system was applied as a plasmonic switch for the high-speed optical amplifier and optical computing using energy-efficient switching and a ripple carrier adder, respectively [19][20][21]. The micro-MUX/DEMUX devices can be applied and linked by the optical cable in the communications [22,23].…”

MUX/DEMUX circuit using plasmonic antennas for LiFi and WiFi uplink and downlink transmission

A microring-embedded Mach-Zehnder interferometer (MZI) system is proposed to form the multiplexing (demultiplexing) for wireless and light fidelity (WiFi and LiFi) uplink and downlink transmission. The system consists of two center microrings at the transmitter and a center microring at the receiver with two small rings along the sides of the center microrings. The whispering-gallery mode (WGM) is formed by the nonlinearity effect induced by the two small rings with suitable parameters. The embedded gold gratings are excited by the WGM, where the plasmon oscillation and electron density are obtained. All possible multiplexing/demultiplexing (MUX/DEMUX) schemes based on space-time input can be applied. The transmission is performed using the tested node. The uplink and downlink input source wavelengths of 1.10 µm and 1.30 µm for LiFi and WiFi are manipulated. The manipulated tested node is employed with a maximum length of 1, 000 km away from the transmitted point via a fiber optic cable. The results obtained have shown that the optimum transmission bit rate of 2.52 Petabit s −1 with the optimum bit error rate (BER) of 0.38 is obtained.

Over the past three decades, silicon photonic devices have been core to the realization of large‐scale photonic‐integrated circuits. However, silicon nitride is another key complementary metal oxide semiconductor‐compatible material for high‐density photonic‐integrated circuits, having low manufacturing costs, low optical losses, and excellent mechanical properties, that can provide enhanced performance over silicon in an integrated photonic platform. This article presents the design, fabrication, and testing of a proof‐of‐concept switchable silicon nitride photonic coupler that leverages these properties combined with microelectromechanical systems actuation. The photonic platform uses a moveable suspended waveguide to enable efficient out‐of‐plane switching and is built using conventional lithographic techniques to demonstrate the high compatibility with existing microelectronic fabrication techniques. The photonic switch is measured to have an insertion loss of 2.6 dB and an ON/OFF extinction ratio of 34 dB at the output of the suspended waveguide, at a wavelength of 1470 nm. Detailed simulations demonstrate broadband operation over a 600 nm wavelength range from 1.25 to 1.85 μm which is experimentally validated over the range from 1.25 to 1.61 μm. To the best of knowledge, this is the broadest operation range ever demonstrated by a photonic switch in simulation.
