Abstract
PURPOSE:To prevent the incidence of the reflected light from a sensor into a transparent window for the stabilization of radiated laser light, by providing an interception plate on the side surface of a chip surrounded thereby when containing a stem and photosensor fixed with a laser diode chip in a package material having a transparent window. CONSTITUTION:The stem 3 is erected on a flange 2 constituted of metal with good thermal conductivity with a lead 11 projecte outside the device fixing the laser diode chip 5 on the upper side surface thereof via a submount plate 4. Next, the lead 11 passed through the flange 2 is provided on the side of the chip 5 in the same way. The following process is taken when arranging the photosensor 7 positioned therebetween and the chip 5 on the flange 2: an opaque interception plate 13 along the side surface of the chip 5 is streatched across over the upper end of the stem 4 including the chip 5 to be fixed on the inside wall of a metallic cap 8 by an adhesive 14.
