An integrated reflecting and focusing structure for use in optical
transmitters and receivers to redirect optical signals when an
optoelectronic device of the transmitter or receiver is positioned in an
off-center relationship with respect to an intended light path is
disclosed. The integrated reflecting and focusing structure simplifies
construction while reducing complexity of the device. In one embodiment,
an optical subassembly is disclosed and includes a housing and an optical
fiber that is coupled to the housing. An optoelectronic component, such
as a laser diode, is positioned in the housing and is configured to
produce a light beam. The subassembly further includes an integrated
focusing and reflecting prism that serves as a means for simultaneously
redirecting and focusing the light beam while in transit between the
laser diode and the optical fiber. The focusing feature combined with
redirection of the light beam obviates the need for a separate lens
assembly.
