Patent ID: 7244068

Claim:
A bi-directional optical module package having an optical module unit comprising: a substrate member; an optical filter installed on the substrate member to be inclined with respect to an optical fiber; a first holder supported by the substrate member on one side of the optical filter and having a laser diode and a lens for transmitting an optical signal to the optical fiber through one side of the optical filter; and a second holder supported by the substrate member on the other side of the optical filter and having a photodiode and a lens for receiving the optical signal received through the optical fiber, wherein the first holder includes a first base portion having a laser diode, a pad and a circuit pattern installed thereon, and first extending portions which extend from both sides of the first base portion to define a fixed position of the lens, and the second holder includes a second base portion having a photodiode installed on an inner surface thereof and a wire bonding pad installed thereon, and second extending portions which extend from both sides of the second base portion to define a fixed position of the lens, and wherein inclined planes having the same gradient as that of an external surface of the optical filter are formed on at least one end portions of the first extending portions and at least one end portions of the second extending portions so that the optical filter is disposed between the inclined planes.
