Speech Title: Optical Ring-core Fiber for OAM-based Communications

Abstract: Optical communications, as the backbone of today’s telecommunications infrastructure, supports voice, video and data transmission through global networks. One critical issue in its research is the challenge of meeting the needs of increasing the data capacity. This talk presents high-speed fiber optical communications using orbital-angular-momentum multiplexing. First, the basics of orbital angular momentum (OAM) and its traditional applications will be introduced. As another newly explored dimension, spatial division multiplexing (SDM) has been demonstrated with the great potential to tremendously increase the data capacity. The building blocks of OAM-based SDM system will be discussed. Next, we will discuss the potential of using orbital-angular-momentum (OAM) modes for spatial multiplexing in a ring fiber. Several types of ring-core optical fibers are presented for OAM modes, including multi ring-core fiber supporting thousands of modes, coupled ring-core fiber with large dispersion, and non-zero dispersion-shifted ring-core fiber to balance dispersion and nonlinearity.

Speech Title: Few Mode Fiber Long-Period Gratings

Abstract: We demonstrate the fabrication of long-period gratings (LPGs) in few mode fibers (FMFs) by using focused carbon dioxide laser. The mode coupling and characteristics of the LPGs written in the FMFs were investigated experimentally and theoretically. The generation and conversion of the orbital angular momentum (OAM) modes were achieved by the special designed gratings. The FMF-LPGs could have promising application as all fiber mode converters for mode-division-multiplexing optical communications and high sensitivity optical sensors.

Abstract: Optical measurement is a fundamental prerequisite of the research and application of light. The optical properties include intensity, polarization state, orbital angular momentum, spectrum, and so on. To measure these properties, people have proposed photodetector, polarimeter, spectrometer, and so on. For a long time, the optical measurement device is built by discrete optical components, which strongly limits the application of optical measurement. Recently, with the development of photonic integrated circuit (PIC) technology, more and more on-chip optical measurement devices have been proposed and demonstrated. In this report, we present our recent works in on-chip polarimeter and spectrometer using silicon PIC. We first introduce how to design an on-chip polarimeter or spectrometer using silicon PIC. And then, we compare the performance of some state-of-the-art optical measurement devices. At last, we provide a future direction of developing on-chip optical measurement devices.
