Embodiment Construction

[0020] Example embodiments of the present invention relate to managing back reflections in various environments including, for example, photonic components. One example embodiment is an OSA including an optical device configured to manage back reflections by partially redirecting optical signals within the OSA. This redirection of the optical signal reduces the likelihood of any back reflections being incident on the optoelectronic transducers within the OSA.

[0021] Example OSAs disclosed herein can be configured, for example, as a Transmitter Photonic Assembly (TOSA) with an optoelectronic transducer for transmitting an optical signal, or as a Receiver Photonic Assembly (ROSA) with an optoelectronic transducer for receiving an optical signal. ). These example OSAs can be integrated into various modules, such as optoelectronic transmitter, receiver, transceiver and / or transponder modules. These modules can be configured to transmit and receive optical signals at various da...

Abstract

In one example, an optical device includes a body 200 having a first surface 202 and a second surface 204. At least a portion of the body is formed from a material that is transmissible to light. The body 200 is configured to be positioned in an optical sub-assembly along an axis defined between an optoelectronic transducer and a port 120 configured to receive an optical fiber The axis is define between a point on an optically active portion of the optoelectronic transducer and a point on a surface of the optical fiber The first surface 202 of the body 200 is positioned at a first angle relative to a plane that is perpendicular to the axis. The second surface 20 the body is positioned at a second angle relative to the plane. The first surface 202 and the second surface 204 are positioned at respective opposing ends of the body.

Description

Background technique [0001] Fiber optic technology is increasingly used in the transmission of data over communication networks. Networks employing fiber optic technology are known as optical communication networks and are generally characterized by high bandwidth and reliable, high-speed data transmission. [0002] For communication over optical communication networks using fiber optic technology, fiber optic components such as fiber optic transceivers or transponders are used to send and receive optical signals. Typically, fiber optic transceivers include one or more photonic assemblies (OSAs) with optical transducers. For example, a transmitter photonic subassembly (TOSA) has an optoelectronic transducer for sending an optical signal, while a receiver photonic subassembly (ROSA) has an optoelectronic transducer for receiving an optical signal. More specifically, a TOSA receives electrical data signals and converts the electrical data signals into optical data signals for ...
