Simulating the detection process of a space-based gravitational wave (GW) measurement system is crucial for the task demonstration, design, operation and data processing. Gaps and glitches, which are common types of abnormal events in the detection process, are an important part of data simulation. This paper explores two gap models and three glitch models, provides a comprehensive overview of these models. The implementation of these models in Taiji Data, the simulation data of the Taiji program, is designed. Dedicated software modules were developed to incorporate the gap and glitch models into the simulation process. The impact of adding gap and glitch to the measurement is illustrated and analyzed. Finally, the time-series simulation detection data of space GWs that integrates gap and glitch models has been obtained, providing support for promoting the improvement of the detection data processing capabilities. © 2023 IEEE.

This work proposes and investigates novel Si1-xSnx alloy-based p-channel split-gate metal-oxide-semiconductor field-effect phototransistors (p-MOSFEPT) designed for near-infrared (NIR) applications. The proposed device is grown epitaxially on the silicon (Si) platform. We utilize Si1-xSnx with x = 3.6% as a virtual substrate (VS) to minimize the lattice mismatch between the Si1-xSnx active layer with x = 30% and the Si substrate. The higher absorption coefficient of the Si1-xSnx active layer leads to improved photoresponse. Furthermore, the implementation of a periodical split-gate structure facilitates the generation and exposure of the channel on the shallow surface, enhancing the efficiency of incident light transmission and absorption, attributed to the surface plasmon resonance (SPR) effect. In this work, the finite-element method (FEM) is employed to analyze the electrical and optical response of the device. The results indicate that the designed device demonstrates the ability to reduce the dark current by 12.5% in comparison to conventional MOSFEPTs. Moreover, the device demonstrates remarkable photoresponse (responsivity, R = ~6×106 A/W) at 850 nm when exposed to an illuminated power of 50 nW. The value obtained represents the highest responsivity when compared to all previously available values. Consequently, there is a strong belief that the proposed phototransistor will find extensive application in NIR bands. © 2025 SPIE.

This paper investigates the problem of local stability for fixed-point interfered digital filters with generalized overflow nonlinearities. First, a familiar form of overflow nonlinearity function, covering the nonlinearities like zeroing, saturation, two's complement, and triangular is established. Second, the asymptotic stability condition for the digital filters is formulated in local context without external interference. Third, with external interference the work is extended to investigate the local stability and to attain H ∞ performance of the digital filter using generalized nonlinearity function. Further, the conventional global stability results can be established as special cases of presented local approach. Finally, sufficient numerical examples are presented to highlight the merit of proposed approach.

Quantum logic gates serve as essential components in quantum computing and communication systems. Literatures highlights the two-state quantum Hadamard gates using various optical techniques. The paper presents an innovative method for developing a quantum-bit Hadamard gate utilizing light's phase encoding approach. The research focuses on the implementation of a silicon nitride-based racetrack configured ring resonator based on polarization rotation phenomena. The Hadamard gate is observed at the resonance wavelength of 1529.5 nm by adjusting the azimuth and elliptical angle of the input polarized light. The proposed polarization-driven Hadamard quantum gate has been confirmed through Jones matrix analysis and numerical simulations.

The emergence of integrated photonic technology provides an attractive solution of high speed, broad bandwidth and strong parallelism for large-scale information transmission and processing in interconnection, communication and computing. Reconfigurability is necessary for photonic processors to adapt varieties of application scenarios in the fields of data exchange, microwave photonics and neural networks. As yet, thermo-optical effect and carrier plasma dispersion effect are the most common phenomena for optical modulation. However, the volatility not only requires continuous power supply to maintain the devices' state, but also accompanies with serious thermal crosstalk induced by active regions. Hence, the nonvolatile methods that can reconfigure and fix on the current state for a long time after a single external excitation are considered as one of the significant technologies in the next generation of integrated photonics. Nonvolatile reconfiguration has been achieved through trapped-charge effect, bistable micro-electromechanical system (MEMS) with nano-latch mechanism and ferroelectric materials, which suffer from high loss, lower stability and complex process flow. Chalcogenide phase change materials (PCM) have become a promising method to realize compact and nonvolatile reconfigurable integrated photonic devices due to the high optical constant contrast between amorphous state and crystalline state, superiorly stable property and low temperature deposition possibility. Here, we developed a monolithic back-end-of-line integration technology of PCM in silicon photonics, supporting "Zero-change"heterogeneous integration platform at wafer scale. On this basis, nonvolatile integrated photonic devices with excellent performance have been fabricated. It lays a foundation for improving the energy efficiency and integration density of integrated photonic processors and suppressing thermal crosstalk between integrated photonic devices. © 2024 IEEE.
