- So far, we've made nanoscale lasers, photodetectors, and ribbons that serve as flexible sub-wavelength optical waveguides.
- As the optical input signal (blue line) to a photodetector increases, the electrical output signal (red line) increases proportionally, and then begins to deviate from linear.
- The rear and front surfaces of an object are covered with a material containing an array of photodetectors and light emitters respectively.
- In the simple experiment, a converging lens focuses laser light from two pinholes onto two different photodetectors.
