Multistability, chaos, and random signal generation in semiconductor superlattices.
Historically, semiconductor superlattices, artificial periodic structures of different semiconductor materials, were invented with the purpose of engineering or manipulating the electronic properties of semiconductor devices. A key application lies in generating radiation sources, amplifiers, and detectors in the "unusual" spectral range of subterahertz and terahertz (0.1-10 THz), which cannot ...

متن کاملMultistability and Chaos in a Semiconductor Microwave Device with Time–Delay Feedback
We propose a tunable microwave device consisting of a Gunn diode with time–delay feedback, which will emit chaotic microwaves. The wavelength is controlled by two incident laser beams which trigger moving multiple Gunn domains. Predicted phenomena include the coexistence of stationary and chaotic states, complicated hysteresis loops, and persistent bistabiliy. This device is potentially useful ...
متن کاملRandom bit generation using an optically injected semiconductor laser in chaos with oversampling.
Random bit generation is experimentally demonstrated using a semiconductor laser driven into chaos by optical injection. The laser is not subject to any feedback so that the chaotic waveform possesses very little autocorrelation. Random bit generation is achieved at a sampling rate of 10 GHz even when only a fractional bandwidth of 1.5 GHz within a much broader chaotic bandwidth is digitized. B...
