Measurements and modeling of a monolithically integrated self-spiking two-section laser in InP

The self-spiking behavior of an integrated saturable absorber and gain section laser fabricated in InP technology platform is analyzed. gain, intensity dynamics are first inspected using the normalized Yamada model. This model shows excitable as well relative refractory period, both which also present biological neurons. Measurements a two-section show irregular spike generation on millisecond timescale, with voltage controlled density. From our simulations, from quasi-random character timescale at these pulses occur, we conclude triggered by noise, important characteristic operation Simulations around excitability threshold newly proposed optical noise term qualitatively similar measured.
