Demonstration of an optoelectronic dual-diode optically controlled optical gate with a 20 picosecond repetition period

摘要

Using surface-normal pulses, a low-power, optically controlled optical gate incorporating two stacked AlGaAs diodes opens and closes within 20 picoseconds with a 30% reflectivity change. Repeated gating with 20 picosecond periods is demonstrated, matching simulations.
