A tunable wavelength-selective filter including a glass substrate, a transparent electrode layer, a high reflective mirror, an alignment layer, a liquid crystal layer, an alignment layer, a transparent material layer whose refractivity index is substantially equal to that of the liquid crystal layer, a high reflective mirror, a transparent electrode layer, and a glass substrate, which are stacked in this order. An etalon cavity of the filter includes two layers, the liquid crystal layer and the glass plate as a transparent material layer, which enables to lengthen the cavity length without increasing absorption and scattering of the cavity. This makes it possible to narrow FWHM, quicken the response time, and increase the transmittance of the filter. As applications of the filter, a double cavity structure tunable wavelength-selective filter of a wide tunable range, and a photodetector of a simple construction can be realized.
