Abstract

PURPOSE:To obtain a small-sized two input light photodetecting device having a high reliability by incorporating the second light source in the same airtight package as a photodetector, and making a light from the first light source incident to the photodetector in the airtight package from an optical fiber. CONSTITUTION:A photodetector 13 and a light emitting element 15 are incorporated in the same metallic airtight package 12. A light from the element 15 is reflected directly or irregularly in the package 12, and thereafter, made incident to the photodetector 13. On the other hand, a light from another light source is emitted from an optical fiber 10, and made incident to the photodetector 13 through a photodetecting window 11. In this regard, the fiber 10 is fixed to the package 12 by supporting metallic fittings, etc. A modulating signal of a light emitted from the element 15 is inputted from a signal input terminal 16, and a modulating signal of a light photodetected by the photodetector 13 is fetched from a signal output terminal 14. In this way, a small-sized two input light photodetecting device which can raise its reliability is obtained.
