Integrated coupling modules for high-bandwidth fiber-optic systems

摘要

An integrated and modular coupling module for coupling light between optical devices, such as an optical fiber connector and optoelectronic device, is presented. In this invention, beam-shaping elements and alignment elements are integrated on a single alignment plate in such a way that they maintain a precise physical relationship. The relative physical arrangement between the beam-shaping elements and the alignment elements are configured such that once the alignment elements are engaged with the peripheral devices, accurate optical alignment between the peripheral devices and the coupling module is also attained. The optical coupling module of the present invention enables it to withstand temperatures of 220° C. or higher while maintaining its integrity and performance. The principle of the present invention can also be extended to constructing coupling modules for coupling other types of electromagnetic radiation.
