Mixed mode oscillations in a forced optoelectronic circuit for pattern and random bit generation

We investigate the generation of mixed mode oscillations in a periodic forced optoelectronic circuit comprising a high-speed resonant tunneling diode (RTD) and a laser diode (LD). The driven RTD-LD exhibits a two-state level operation, characterized by either periodic or aperiodic intermittent patterns with a high amplitude followed by small amplitudes, that can be used for applications in switching at very fast modulation speeds and encoding of binary data sequences into the corresponding electrical and optical states of the dynamical system.
