Abstract: A light detection device includes a Fabry-Perot interference filter provided with a light transmitting region on a predetermined line, a light detector disposed on one side with respect to the Fabry-Perot interference filter on the line, a package having an opening positioned on the other side with respect to the Fabry-Perot interference filter on the line, a light transmitting member provided in the package such that the opening is blocked, and a temperature control element having an endothermic region thermally connected to the Fabry-Perot interference filter and the light detector. The endothermic region is positioned on one side with respect to the light detector on the line.

Abstract: A method of manufacturing a Fabry-Perot interference filter includes a forming step of forming a first thinned region, a first mirror layer, a sacrificial layer, and a second mirror layer are formed on a first main surface of a wafer, and the first thinned region in which at least one of the first mirror layer, the sacrificial layer, and the second mirror layer is partially thinned along each of a plurality of lines is formed; a cutting step of cutting the wafer into a plurality of substrates along each of the plurality of lines by forming a modified region within the wafer along each of the plurality of lines through irradiation of a laser light, after the forming step; and a removing step of removing a portion from the sacrificial layer through etching, between the forming step and the cutting step or after the cutting step.

Abstract: A light detection device includes: a Fabry-Perot interference filter provided with a light transmission region; a light detector configured to detect light transmitted through the light transmission region; a package having an opening and accommodating the Fabry-Perot interference filter and the light detector; and a light transmitting unit arranged on an inner surface of the package so as to close an opening, the light transmitting unit including a band pass filter configured to transmit light incident on the light transmission region. When viewed from a direction parallel to the line, an outer edge of the Fabry-Perot interference filter is positioned outside an outer edge of the opening, and an outer edge of the light transmitting unit is positioned outside the outer edge of the Fabry-Perot interference filter.

Abstract: A Fabry-Perot interference filter 10A includes a first mirror 31; a second mirror 41 being opposite to the first mirror 31 with a gap S therebetween; a first electrode 17 formed in the first mirror 31 to surround a light transmission region 11; a second electrode 18 formed in the first mirror 31 to include the light transmission region 11; and a third electrode 19 formed in the second mirror 41 to be opposite to the first electrode 17 and the second electrode 18 and connected to the same potential as the second electrode 18. The second electrode 18 is positioned at the side of the third electrode 19 or the opposite side thereof with respect to the first electrode 17 in an opposite direction D where the first mirror 31 and the second mirror 41 are opposite each other.
