Simultaneous Measurement of Temperature and Surrounding Refractive Index by Combining A Fiber Bragg Grating and A Mach-Zehnder Interferometer
We have fabricated a compact bi-parameter sensor by splicing a fiber Bragg grating (FBG) with two single-mode fibers with misalignment to form Mach-Zehnder interferometer (MZI) structure. The transmission dips corresponding to the FBG and MZI can be successfully observed to simultaneously detect the variations in temperature and surrounding refractive index.

Timing-mismatch tolerance of all-optical modulation format conversion from NRZ-OOK to PDM RZ-QPSK based on XPM in a HNLF
We proposed and experimentally demonstrated an all-optical modulation format conversion mechanism from 4 individual 12.5 Gbps to a 50 Gbps PDM RZ-QPSK by applying bidirectional cross-phase modulation (XPM) in a single HNLF. Besides, the timing-mismatch tolerance among all the signals in the proposed format converter is further analyzed.

All-Fiber Curvature Sensor Based on Liquid Crystal Mach-Zehnder Interferometer
A high-sensitive fiber curvature based on the Mach-Zehnder Interferometer (MZI) is proposed and experimentally demonstrated by simply fusion splicing a section of hollow-optic fiber (HOF) filled with liquid crystal (LC) between two single mode fibers (SMF). The curvature performance is characterized by measuring the wavelength shifts and intensity changes. A nonlinear of the wavelength “blue shift” and minimum transmission is observed when we increase the curvature. The high sensitivities of wavelength shift-curvature and intensity-curvature are obtained

We propose a new fabrication method to produce microtoroid resonators on LiNbO3. The LiNbO3 microdisks are first produced by utilizing RF sputtering, chemical etching, photolithography and selective ion implantation. Then the reverse-side thermal reflow is used to thicken the microdisk edge to form the microtoroid. The measured intrinsic Q factor is 2.2×104.

Microwave Bandpass Filter Using Fabry-Perot Laser Diode
A microwave bandpass filter was developed using a self-injection Fabry-Perot laser. The microwave filter consisted of a Fabry-Perot laser diode, an optical tunable filter, and an optical amplifier. The optical tunable filter can be flexibly used to adjust the 3 dB bandwidth of a microwave bandpass filter. The experimental results demonstrate that the proposed microwave filter is simple and effective.
