Competition between sub-bandgap linear detection and degenerate two-photon absorption in gallium arsenide photodiodes
This letter is on the response of gallium arsenide p-i-n diodes to sub-bandgap photons (1.55 μm). We investigate the various regimes of sub-bandgap operation by using different light sources delivering pulses ran...
