Multicore composite single-mode polymer fiber
Optics Express, 2011 We study, fabricate and characterize an all-solid polymer composite waveguide consisting of a multicore fiber for single-mode operation down to the visible. The individual cores of the multicore structure are arranged such that they strongly interact, to form the composite core.

Breaking the speed limitation of wavemeter through spectra-space-time mapping
Light: Advanced ManufacturingSpeckle patterns generated by the intermodal interference of multimode fibers enable accurate broadband wavelength measurements. However, the measurement speed is limited by the frame rate of the camera that captures the patterns.

Quantum key distribution over multicore fiber
Optics Express, 2016 We present the first quantum key distribution (QKD) experiment over multicore fiber. With space division multiplexing, we demonstrate that weak QKD signals can coexist with classical data signals launched at full power in a 53 km 7-core fiber, while showing negligible degradation in performance.
