An optoelectronic device may include an insulating substrate, a semiconductor channel region located on the insulating substrate, and a source region and a drain region in contact with the semiconductor channel region. A photoswitchable material may be located on the semiconductor channel region between the source region and the drain region, such that the photoswitchable material includes a first structural state based on being exposed to a first optical wavelength, and includes a second structural state based on being exposed to a second optical wavelength. The first structural state causes a first electrical current to flow between the source region and the drain region, while the second structural state causes a second electrical current to flow between the source region and the drain region.
