Signal beating elimination using single-mode fiber to multimode fiber coupling
TL;DR: An all-passive fiber-based approach to prevent undesired beating during signal merging and detection is experimentally demonstrated, resulting in widely opened eye diagrams and error-free bit error rate performance.

Spiral-structured fiber Bragg grating for contact force sensing through direct power measurement.
TL;DR: A high-sensitivity fiber Bragg grating (FBG) force sensor based on direct optical power measurement is presented, using a novel structure where the FBG is mounted on a thin tube-like fixture spirally, enabling real-time contact force monitoring.

Demonstration and Analysis of Asynchronous and Survivable Optical CDMA Ring Networks
Yanhua Deng,Zhenxing Wang,Konstantin Kravtsov,John Chang,Carolyn Hartzell,Mable P. Fok,Paul R. Prucnal +6 more
TL;DR: An incoherent optical code-division multiple access (CDMA) ring network configured such that each node in the network includes all-optical add/drop multiplexers to provide truly asynchronous operation and a self-healing protection monitoring circuit to ensure service availability during link failure is proposed.

Temperature-Insensitive Fiber-Optic Contact Force Sensor for Steerable Catheters
TL;DR: In this paper, a fiber Bragg grating (FBG) is used as the sensor, which is very small and can be fixed on the outer arc of a steerable catheter, such that it does not occupy any space inside the catheter.

Power Transfer Function Tailoring in a Highly Ge-Doped Nonlinear Interferometer-Based All-Optical Thresholder Using Offset-Spectral Filtering
Nicole Rafidi,Konstantin Kravtsov,Yue Tian,Mable P. Fok,Mitchell A. Nahmias,Alexander N. Tait,Paul R. Prucnal +6 more
TL;DR: In this article, offset spectral filtering was used to adjust the power transfer function and thresholding slope of a Gaussian nonlinear interferometer-based thresholder to improve the performance.
