Abstract:
A photodetector detects the absence or presence of light by detecting a change in the inductance of a coil. The magnetic field generated when a current flows through the coil passes through an electron-hole generation region. Charged particles in the electron-hole generation region come under the influence of the magnetic field, and generate eddy currents whose magnitudes depend on whether light is absent or present. The eddy currents generate a magnetic field that opposes the magnetic field generated by current flowing through the coil.
