We demonstrate two-photon absorption (TPA) photocurrent in p-i-n diode embedded silicon microdisk resonators. Our experiments reveal TPA photocurrent spectra with peaks corresponding to the microdisk resonance modes. The photocurrents at resonance wavelengths exceed those at off-resonance wavelengths by up to three orders of magnitude. We study the microdisk photocurrent spectra with various p-i-n diode intrinsic region widths in the microdisk rim. We report TPA photovoltaic effect with maximum… CONTINUE READING
