Simultaneous Measurement of Shape and Temperature in the Substrate-Attaching-Fibers Sensing System
IEEE Photonics Journal, 2017 We design a dual-parameter sensor which can simultaneously measure the shape and temperature in the substrate-attaching-fibers sensing system. Two kinds of fibers with different diameter are attached on a shape memory alloy wire substrate with an angle ...

High energy green nanosecond and picosecond pulse delivery through a negative curvature fiber for precision micro-machining [PDF]
, 2015 In this paper we present an anti-resonant guiding, low-loss Negative Curvature Fiber (NCF) for the efficient delivery of high energy short (ns) and ultrashort (ps) pulsed laser light in the green spectral region.

Ultrabroadband dispersive radiation by spatiotemporal oscillation of multimode waves [PDF]
, 2015 Despite the abundance and importance of three-dimensional systems, relatively little progress has been made on spatiotemporal nonlinear optical waves compared to time-only or space-only systems.

Hardware-Efficient Phase Estimation for Digital Coherent Transmission With Star Constellation QAM
IEEE Photonics Journal, 2010 In order to build optical transmission systems for 100 Gb/s and above on a single wavelength division multiplexing channel, transition from quadrature phase-shift keying (QPSK) to higher quadrature amplitude modulation (QAM) formats seems to be ...

Toward a compact fibered squeezing parametric source
, 2018 In this work, we investigate three different compact fibered systems generating vacuum squeezing that involve optical cavities limited by the end surface of a fiber and by a curved mirror and containing a thin parametric crystal.
