Robust and Portable Microresontor Sensor Coupling Design

Case ID:

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.


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.



  • Optical resonators
  • Sensor systems
  • Telecommunications


  • Less expensive and faster to produce than conventional tapered optical fiber couplers
  • More robust and portable than regular optical fibers
  • Not prone to breakage
  • Can be produced in mass quantities
