We propose a novel method to mitigate the power fading effect in a V-band fiber-wireless 3x3 MIMO system. The proposed scheme can realize the 114.71-Gbps RoFMF system with 1.7-m FMF and 3-m wireless transmission.

 

A hybrid fiber sensing scheme is built by setting a Brillouin-optical-time-domain-analysis (BOTDA) fiber system and two Fiber Bragg gratings. The proposed system is capable of 16km sensing distance with a 2m spatial resolution. For FBGs parameters measurement, the measured sensitivity of 23pm/C and 0.975pm/με for temperature and strain individually.

 

A symmetrical polarization-division-multiplexing (PDM) wavelength-division-multiplexing passive optical network (WDM-PON) together with fiber to the extension link is designed. The investigated PDM WDM-PON architecture not only provides 35 Gbit/s downstream data traffic, but also avoids the Rayleigh backscattering (RB)-produced beat noise.

 

We investigate a wavelength-switchable quad-ring (QR) based erbium-doped fiber (EDF) laser to accomplish single-longitudinal-mode (SLM) exhibition. The presented QR can cause a mode-filter effect to mitigate the thick multi-longitudinal-mode (MLM), flatten power output and narrow wavelength linewidth over an obtainable tuning scale of 1524.0 to 1569.0 nm.

 

We propose to use a multi-ring architecture in erbium-doped fiber (EDF) based fiber to reach switchable wavelength and stable single-longitudinal-mode (SLM) behavior. Here, based on C-band erbium gain regarding as gain medium can extend the tuning scale from 1519.0 to 1577.0 nm. The related output characteristics are also executed.

 

We present an integrated path-encoded quantum optical controlled-NOT (CNOT) gate implemented on a Si3N4 photonics platform. The miniaturization of such a quantum logic gate on a chip is achieved by integrating reconfigurable Si3N4 Mach-Zehnder interferometer (MZIs), which replace bulk beam splitters that are commonly used on optical tables.

 

We propose a simple approach to modify the structure of hollow core antiresonant nodeless fiber (HC-ANF) by introducing connecting rods between the inner and the outer tubes of HC-ANF. Confinement loss of the modified HC-ANF with connecting rods can be lowered nearly one order of magnitude.

We design a high-speed inductive-peaking Si microring modulator (MRM) which has a spiral inductor to enhance electro-optic conversion efficiency. Via properly selecting the operating wavelength, the MRM’s 3dB bandwidth extends from 45GHz to over 65GHz and the conversion gain increases by 5 dB at 50 GHz.

 

A high-efficiency polarization beam splitter is proposed by using three-waveguide coupler with subwavelength grating waveguide. The coupling length is only 12 μm, and the operation bandwidth is 53 nm. In addition, our proposed structure also possesses good fabrication tolerance.

 

We use MatLab to simulate the coupling efficiency between optical fiber and waveguide. Then, report and demonstrate the hyperboloid micro-lensed from Si-photonics chip coupling to single-mode fiber employing automatic grinding and calibrated spin-on-glass coating techniques

 

Recently, metalens has received significant attention because of its ability to control the light. In order to achieve mass production and high production yield rate, we develop an optical proximity correction simulation suite with fully convolutional network to enable the patterning of near-infrared metalens using the i-line photolithography. A 1.5mm metalens with a numerical aperture of 0.45 has been successfully fabricated with a measured efficiency over 50%, which is among the highest reported values using i-line photolithography.
