Title: Robust and Portable Microresonator Sensor Coupling Design


Invention: This technology is a novel design for an optical coupler that is more robust, easier to fabricate, and not as fragile as a regular coupler.  This technology has great potential for portability due to it’s robust design and does not require tapered optical fibers with high nano-positioning requirements, making it easier to mass produce.


Background: Regular optical resonator sensor systems use fragile optical fibers, which are prone to breakage at the coupler port if not properly cared for, making them non-portable. In addition, current optical coupler designs require tapered optical fibers with high nano-positioning requirements, which have to be carefully fabricated.
