A freeform DOE for use in an optical transmitter and a method of designing and manufacturing the DOE are provided. The freeform DOE is capable of achieving the same, or nearly the same, functionality as that of a glass DOE, but has a design that has been transformed to make the surface profile of the DOE compatible with a molding process that can be used to manufacture the DOE with high quality at low costs. The method of designing and manufacturing the DOE includes preselecting a CGH that will obtain a target freeform DOE design, using a preselected smoothing function to smooth the surface profile of the target freeform DOE design to transform the design into a DOE design that is compatible with a molding process, and using a fabrication process to manufacture a freeform DOE that is based on the transformed DOE design.

An optical communications module is provided that has WDM capabilities for increased bandwidth and that is suitable for use with single mode optical fiber or multimode optical fiber. The module can be configured to have both WDM and BiDi functionality to further increase bandwidth and can have a single- or multi-channel configuration. The module has an integrally-formed body having an optical port and portions of an optical coupling system that are integrally formed in the body. The optical port is adapted to mate with an end of an optical fiber cable that holds one or more ends of one or more optical fibers, depending on whether the module is a single-channel or multi-channel module. The optical coupling system couples light between an end or ends of one or more optical fibers and one or more optoelectronic devices in a way that reduces back reflection and mode partition noise.

Wavelength division multiplexing and demultiplexing in optical communications modules, and methods

A device, system, and method of attaching fiber optics to a transceiver are provided. Specifically, a connector module may include a fiber input angled relative to a lens groove or set of grooves such that the inherent stiffness of the fiber can be used to provide a positive pressure of the fiber when attaching the fiber to the groove or set of grooves.

Fiber to lens attach device, system, and method

A method is disclosed by which precision alignment of optical fiber to wave-guide or other optical elements can be carried out with an adjustable microstructure in active alignment mode fiber attachment. A microstructure containing three elongated U-grooves can be combined effectively to produce a movable and adjustable V-groove structure, which can be used to achieve sub-micron scale alignment control with zero rotational torque. This device not only makes fiber alignment easy and fast but also maintains the fiber attachment position after alignment and epoxy bonding. Multiple fiber array alignment can be carried out with only a global alignment of two end fibers.
