Notes:
A p-n homojunction GaAs-based photodetector is developed in order to operate in the near field of a subwavelength sized light source. It has a spatial resolution of about 270 nm, limited by diffusion of minority carriers. A detector with a built-in AlGaAs diffusion barrier is also studied, demonstrating an improved resolution of better than 100 nm. © 1994 American Institute of Physics.
