Analysis of subharmonic phase control in cavity-coupled resonant tunneling diode oscillators
This work proposes an efficient semi-numerical scheme to simulate phase and frequency modulation in noisy resonant tunneling diode (RTD) oscillators coupled to parasitic cavity modes. Using a separation of timescales, a compact amplitude-phase description of the coupled system is derived. In this compact system, phase modulation by fundamental and subharmonic injection locking is investigated regarding the influence of amplitude- and phase noise, the influence of external cavity modes and the limitations in the modulation bandwidth and stability. The stability of phase control against cycle slips induced by the phase modulation is expressed using a diffusion coefficient. The compact system accurately models experimental data of RTD oscillators presented in this paper, which show a strong correlation of module integration on frequency and phase control at oscillation frequencies of 550 GHz. The method lays a foundation for compact and dynamic phase-amplitude descriptions of cavity-coupled RTD oscillators and arrays for future applications in localization and sensing, in which the interaction between the RTD and external resonance modes is decisive.
期刊介绍：
he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered.
In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
