Hybrid optical bistability based on increasing absorption in depletion layer of an Si Schottky SEED device
A novel experiment on cavityless hybrid optical bistability observed in the depletion layer of an Si Schottky SEED at room temperature and CW optical input at a wavelength of 1.06 micron from a Nd:YAG laser is reported. The experimental results show bistability both in the optical transfer characteristics and in the photocurrent of the device. The induced absorption is largely enhanced by electrooptical feedback. Resonant or coherent light is not necessary for the device, which can be controlled by the applied bias voltage.
