An optical fiber Bragg grating (FBG) temperature sensor based on microwave photonic filtering technique is proposed and demonstrated. A single bandpass microwave photonic filter (MPF) which mainly contains a tunable laser source (TLS), a phase modulator (PM) and a uniform temperature sensing FBG is demonstrated. When the uniform temperature sensing FBG is experiencing a temperature variation, the notch frequency in its reflection spectrum is shifted, leading to a large passband frequency change of the single bandpass MPF. Hence, by measuring the passband frequency, the temperature can be deduced. In this scheme, a high sensitivity temperature sensing with a sensitivity of 1.7641 GHz/°C is achieved. Since a small wavelength variation can induce a large passband frequency change, the performance with respect to the resolution is dramatically increased. In addition, the measurement error of the proposed optical FBG temperature sensor is less than 0.3 °C.

In this work, we report a dense heterogeneous integration of III-V/Si phase shifters for optical phased arrays. The phase shifters have a V2π of 0.9 V and optical loss of 0.15 dB at 1550 nm for 2π phase shift with low power consumption of less than 3 nW. We integrate those phase shifters in optical phased arrays with a pitch of 4 µm and the number of channel up to 240. 2D beamsteering is also demonstrated in a 32-channel optical phased array.

A low-threshold random fiber laser based on an array of weak-reflectivity chirped-fiber Bragg gratings (CFBGs) written in a 5-m-long erbium-doped fiber incorporating with a wavelength-matched high-reflectivity CFBG in a half-open cavity is demonstrated. Pumped with a 980 nm laser, typical random laser radiation is obtained with low threshold power of only 4.3 mW and a slope efficiency of 11.2%.

A localized surface Plasmon resonance (LSPR) biosensor using gold nanosell immobilized excessively tilted fiber grating (ExTFG) was proposed, the limit of detection (LOD) of the biosensor for bovine serum albumin (BSA) is 0.075pM.
With the distributed-side-coupled cladding-pumped (DSCCP) fiber of independent design, we firstly demonstrated a 3-kilowatt distributed side-pumped oscillator, to the best of our knowledge. An output power of 2.95 kW with a slope efficiency of 77.4% is obtained (M2 ≈ 2.04). No stimulated Raman scattering (SRS), transverse mode instability (TMI) and amplified spontaneous emission (ASE) component is observed in the output spectra.
