- By adjusting an infrared laser power illuminated onto a vanadium dioxide (VO 2) thin film, we have demonstrated laser-assisted control of field-induced electrical oscillation in a planar junction device based on a VO 2 thin film. Before the illumination, the VO 2-based two-terminal device was arranged in the electrical circuit for creating the field-induced oscillation. With the increase of the illumination power, the oscillation could be initiated, and the oscillation frequency could be also continuously and fully tuned until the extinguishment of the oscillation through the variation of the light power. The tuning sensitivity and linearity of the oscillation frequency with respect to the illumination power were evaluated as ~7.732 MHz/W and ~ 0.9903 (an R -squared value of a linear fit), respectively. © 1983-2012 IEEE.
