We have demonstrated a long distance distributed vibration fiber-optic sensing system based on phase-sensitive optical time-domain reflectometer (φ-OTDR). Without any additional components, vibration detection utilizing heterodyne detection and digital coherent detection is successfully demonstrated over a 50-km-long optical fiber and the external disturbance signal simulated by PZT is well restored with signal-to-noise ratio (SNR) of ∼32.8 dB through phase difference method. For the first time, the distributed vibration sensing based on phase-extraction is realized in optical fiber over such a long distance. This measuring technique is ideal for applications in fields of oil and gas pipeline monitoring, national borders and can be further optimized to realize the longer sensing distance.

Multiwavelength Brillouin Erbium fiber laser with ultra-narrow bandwidth filter is used as a temperature sensor. It has less than 10−3 °C resolution at the 3rd-order Stokes in the short term. 3.104 MHz/°C sensitivity of the 3rd-order Stokes wavelength are demonstrated, which is three times that of the 1st-order Stokes wavelength. A less than 0.2 °C temperature error is obtained for every Stokes wavelength. This proposal can provide a feasible temperature sensing scheme with high sensitivity, high precision and low frequency detection.

A thulium-doped fiber chirped pulse amplifier (FCPA) is presented and used to pump a ZrF4-BaF2-LaF3-AlF3-NaF (ZBLAN) fiber for mid-infrared supercontinuum generation. The FCPA delivers 10 W average power at repetition rate of 10 MHz with pulse width of 252 fs. The pulses are coupled into 10 m ZBLAN fiber using an aspheric lens. Maximum output power of 800 mW corresponding to pulse energy of 80 nJ has been obtained with 5 dB spectrum ranging from 2 μm to 3.5 μm, which is limited by the low pump coupling efficiency of ∼10% at this time.

We report on noninvasive characterization of MNs' real-time swelling property in mice-skin using a lab-built micro-optical coherence tomography (μOCT). Specifically, we propose to encapsulate the iron-oxide (Fes3O4) nanoparticles into polymeric MNs as contrast agent to enhance OCT image contrast, and then evaluate its influences on contrast enhancement quantitatively. The MNs' real-time temporal swelling behaviors in mice-skin are recorded and analyzed. This is the first quantitative study on MNs' temporal swelling property in biological tissue using μOCT.

We proposed a normalized model to describe the general behaviors of polarization pulling in fiber optical parametric amplifiers (FOPAs). We adopted a modified interpolation function to analyze the simulation results and found that FOPAs using fibers with moderate PMD coefficient can achieve strong polarization pulling with relatively small gain.

We demonstrate high-speed modulations in dual-polarization (DP) quadrature phase shift keying and DP 16- and 32-quadrature amplitude modulation formats with radio frequency driving voltage as low as 2 Vppd using a packaged monolithic silicon DP in-phase quadrature modulator that employs a highly efficient vertical p-n junction rib-waveguide phase shifter.

We demonstrate the high resolution beam steering of a highly dispersive VCSEL-based amplifier. By using p-type GaAs substrate, the uniform current injection was carried out for 1mm long device and we obtained the maximum deflection angle of 33° and a beam divergence angle of 0.08° resulting in resolution points of over 300.

We investigated specific common optical parametric generation (OPG) using a 532nm pump beam along the x axis of a square lattice two-dimensional periodically poled lithium tantalate (2D-PPLT). Twin-beam generation are observed with the signal or the idler beams propagating collinearly and the other OPG counterpart non-collinearly to the pump beam due to participation of reciprocal lattice vectors (RLV) of K1,±1. Multi-wavelength dual-beam generation are also observed due to contributions from K1,0 and K1,±1.

In this letter, we demonstrated a 1×4 folded silicon photonics arrayed waveguide grating integrated with ring-mirrors at the end of arrayed waveguides on SOI platform. Each reflective ring-mirror is composed of a 1×2 MMI splitter/combiner and a bend silicon nanowire waveguide in the end of each arrayed waveguide. Compared to a normal arrayed waveguide grating, the structure of the ring-mirror-integrated arrayed waveguide grating is only half. The measured transmission loss is about 3.5 dB and the crosstalk is around 20 dB. The measured channel spacing is 6.7 nm.
