A new kind of wavelength selective photoreceiver is proposed. It was constructed by a Fabry Perot (F P) etalon filter and a resonant cavity enhanced (RCE) photodetector. The photoreceiver′s spectral response is determined by the F P etalon filter with a FWHM of less than 4 nm. Moreover, with such a photoreceiver, the transmission loss of the F P etalon filter can be compensated to some extent. And this will benefit its applications.
