Abstract:
A heat sinking laser diode package, comprising:a laser diode; more than one thick metal plates serving as external leads connected to said laser diode and as a substrate for mounting said laser diode, wherein said laser diode is mounted on a first metal plate of said thick metal plates serving as the lead for the bottom electrode of said laser diode, and the top electrode of said laser diode is wire-bonded to a second metal plate of said solid metal plates serving as the lead for the top electrode of said laser diode; a glue for sealing said laser diode and for aggregating said metal plates with said laser diode as a unitary structure; and a photo diode mounted on said first metal plate of said thick metal plates to monitor the light emitted from said laser diode, wherein said first metal plate serves as a first electrode for said photo diode and the top electrode of said photo diode is wire bonded to a third metal plate of said thick metal plates serving as a lead for said photo diode, and wherein said first metal plate has a lower step for mounting said photo diode, so as not to block the light emitted from said laser diode.
