In this study, a smoke detector based on plasmon-polariton photodetector (PPPD) is proposed to address the issue of false triggering in optical smoke detectors under conditions of high room dustiness. The proposed detector uses a PPPD based on a p-n junction in a silicon wafer, on which a metal grating is fabricated by interference photo-lithography technology for surface plasmon-polariton resonance excitation. The design of the smoke detector based on PPPD has been developed to enable the production of a relatively compact and inexpensive device. As a result of optimizing the PPPD parameters, the following characteristics of experimental samples with Au and Al gratings were achieved: the maximum polarization sensitivity Ip /Is ranging from 3 to 8, the spectral and angular half-widths of the photocurrent resonance range from 50 to 200 nm and from 5° to 10°, respectively, and photosensitivity at the resonance maximum Iph = 0.04...0.1 A/W.
