A large diameter fiber-optics tweezers was proposed and demonstrated for trapping and delivering E. coli bacteria. The tweezers was formed by a tapered four-mode fiber (FMF) with the diameter of 8 µm, causing the resonance field of the high-order mode extension to the ambient for manipulating the micro-objects. The diameter of the FMF taper was much larger than that of previous nano-fiber device, making it work as a sturdy tweezers. At the wavelengths ranging from 1500 nm to 1600 nm, especially close to 1560 nm, the E. coli trapping and delivering along the fiber were observed apparently. The method of higher-order micro-fiber modes offers a new opportunity for better using optical manipulation at the single-cell level.

In this study, a polarization rotator (PR) with a simple structure distribution based on square lattice photonic crystal fiber (PCF) has been proposed. The unit cell in the cladding is designed of two circular air holes that are distributed along the diagonal. Simulation result illustrates that a polarization conversion efficiency of 99.4% is obtained with a device length of 53:2 μm at wavelength of 1:55 μm. Additionally, the structural tolerance and wavelength dependence of the proposed PR are also discussed in detail.

A relative humidity (RH) sensor is proposed using a microfiber coupler (MFC) coated a single layer of Molybdenum disulfide (MoS2) nanosheets. The microfiber coupler with a waist diameter of approximately 6 um is manufactured using flame heating technology. The effective refractive index of MoS2 changes due to electric charge transfer when water molecules are adsorbed on MoS2 nanosheets. It will affect the interference conditions of MFC. The results show that the sensitivity of the sensor is 115.3 pm/%RH and it shows a good linear relationship in the range of 54.0%RH-93.2%RH. The proposed sensor is expected to be used for humidity measurement in the fields of biomedicine and chemistry.

We have successfully observed ~ 1.3 μm whispering gallery modes from a Si-based rolled-up InAs/GaAs bilayer quantum dot (BQD) microtube at room temperature. The BQD microtube is first made by selectively releasing the InGaAs/GaAs strained bilayer from GaAs substrate and then transferred on a SiO2/Si substrate using substrate-on-substrate transfer technique. Room-temperature microphotoluminescence spectrum features that six sharp and regularly spaced peaks locating in the wavelength range of 1150–1350 nm and the max Q-factor is ~ 1100 under an excitation power of 230 μW.
