Collecting Telecom Photons From Circular Bragg Gratings Using Optical Fibers and 3D Printed Micro‐Lenses

Advanced Quantum Technologies, Volume 8, Issue 11, November 2025.
Coupling quantum light into optical single‐mode fibers is a strict requirement for quantum technological implementations. This work experimentally quantifies coupling efficiency of telecom single‐photons from circular Bragg grating cavities into silica fibers even equipped with 3D‐printed micro‐lenses.

Embedded 45° micro-mirror for out-of-plane coupling in optical PCBs [PDF]

, 2008
We present an embedded 45° micro-mirror that can be used to couple light out-of-plane of the optical layer. The discrete micro-mirror is inserted in a micro-cavity into the optical layer.
