Abstract
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.
