Abstract
This disclosure generally relates to high-speed fiber optic networks that use light signals to transmit data over a network. The disclosed subject matter includes devices and methods relating to multi-lens optical components and/or optoelectronic subassemblies. In some aspects, devices and methods relate to an optical component including a housing defining a cavity and a lens array having a plurality of lenses on an optically transmissive portion of the housing. In some aspects, devices and methods relate to an optical component including a substrate; and a lens array on the substrate, the lens array having a plurality of discrete lenses.
Claims16
An optoelectronic subassembly comprising:
- a multi-channel header subassembly comprising:
- a substrate;
- and
- optoelectronic components coupled to or formed on the substrate, the optoelectronic components configured to transmit and/or receive multiple optical signals each corresponding to one channel;
- and
- an optical component coupled to the header subassembly, the optical component comprising:
- a circular housing extending between a housing top and a housing bottom, the housing top defining an aperture sized and shaped to receive a corresponding circular ferrule assembly such that the ferrule assembly is rotatable when positioned at least partially in the aperture;
- a window in the aperture that is at least partially optically transmissive such that the window permits the optical signals to travel between the ferrule assembly and the header subassembly through the optical component positioned there between;
- a lens array including lenses configured to convey the optical signals each corresponding to one channel;
- and
- a cavity defined by the housing and the window, the cavity hermetically sealing portions of the header subassembly.
A method comprising:
- providing an optical component including a housing defining a cavity and an aperture, the optical component including a lens array having a plurality of discrete lenses on an optically transmissive portion of the housing;
- positioning the optical component over a header subassembly, the header subassembly including a substrate and optoelectronic components on the substrate, wherein at least one of the optoelectronic components is configured to transmit and/or receive optical signals and is optically aligned with the lens array;
- hermetically sealing the optoelectronic components in the cavity of the housing;
- inserting a ferrule assembly including optical fibers at least partially into the aperture;
- and
- rotating the ferrule assembly with respect to housing when the ferrule assembly is positioned at least partially in the aperture.
