A Schottky contact detector comprising a symmetric metal stripe buried in Si, capable of detecting surface plasmons at wavelengths below the bandgap of Si, is described. A model for the detector is proposed, and its performance is assessed at λ 0 = 1550   nm assuming a CoSi 2 stripe in p-type Si. End-fire coupled responsivities of about 0.1 A/W and minimum detectable powers of about −20 dBm are predicted at room temperature.
