Research

  • Optical Fiber Communication

  • 1. Optical signal processing

    As the continuous growth of technology in laser sources, fiber fabrication and receiver design, the way of signal transmission through optical fibers changes from single wavelength to wavelength division multiplexing, from inefficient mechanism of time usage to time division multiplexing, and from single format transmission to mixed formats transmission, etc. All of these changes lead to the increasing transmission speed per channel from hundreds of Mb/s to over 10 Tb/s. With the increasing transmission speed, the processing of the optical signal becomes more difficult and complicated. At low transmission speed, the optical signal is usually converted to electrical signal and then back to optical signal after electrical signal processing. This is the so called O/E/O conversion. However, at high transmission speed the electrical signal processing reaches its limits as it relies on the mobility of electrons in semiconductor materials. To overcome the bottleneck of electrical signal processing, all optical signal processing based on optic-electric effects or nonlinear optical effects, which exploits photons propagating with the speed of light and directly processes the optical signal, provides a power-efficient way of processing high speed signal without O/E/O conversion. The optical signal processing have the potential to operate in the femtosecond time domain and thus the processing speed is far beyond the limitation of electronic devices. Therefore, optical signal processing would be a desirable candidate for future high-speed fiber-optic networks.

    2. Optical tranmission system

    With the transmission capacity increase, optical coherent technologies have attracted a large interest over the recent years. The motivation lies in finding methods of meeting the ever-increasing bandwidth demand with multilevel modulation formats based on coherent technologies. Using multilevel modulation formats can exponentially increase the bit rate while keeping the symbol rate, and any kind of multilevel modulation formats can be introduced by using coherent receiver because coherent detection can recover both the amplitude and phase of the optical carrier. On the other hand, the recent development of high-speed digital integrated circuits opens a way for high-speed digital signal processing (DSP). The combination of coherent detection and DSP circuits enables fast recovery of the complex amplitude of the optical carrier with multilevel modulation formats in a very stable manner. More importantly, this digital coherent receiver offers the advantage of post signal-processing function. For example, the optical filtering and dispersion compensation, which are usually done in optical domain, can now be achieved in electrical domain by simple computer programmes. Transmission impairments due to fiber nonlinearities can also be compensated at the electrical stage by appropriate adaptive equalization algorithm. Post signal-processing based on DSP has become a new trend of optical communications and thus the digital coherent receiver enables more sophisticated signal processing functions.


  • Optical Fiber Sensing

  • 1. Conventional fiber sensor

    In parallel with the developments in fiber-optic communications, fiber-optic sensor technology has been well advanced since the technology shares almost the same components as those used in fiber-optic communications. Many of the components associated with fiber-optic communications are often employed for fiber-optic sensor applications. In turn, fiber-optic sensor technology has also promoted the development and subsequent mass production of components to support these industries. The potential of fiber-optic sensor in replacing other kinds of traditional sensors has been enhanced due to the reduction in component prices and the improvement on component quality. Therefore, although in the early days, fiber-optic sensors were deployed in places where traditional sensors were marginal or nonexistent, the situation has been changing. Fiber-optic sensors are now widely deployed for measurements, such as electric and magnetic field measurement, temperature, strain, linear and angular position, humidity, viscosity, chemical measurements, etc. As these trends continue, the fiber-optic sensor technology will ensure a full frame of sensor networks around the world, providing prominent detection and measurement for nearly all fields of our life.

    2. Distributed fiber sensor

    Distributed fiber-optic sensors take the advantage of the high intrinsic bandwidth of the optical fibers and allow all locations along the long single optical fiber to be measured simultaneously. The distributed sensing scheme far exceeds the capacity of other schemes relying on multiplexing the measured results from all the single point sensors. In a distributed fiber-optic sensor system, the optical fiber not only acts as the sensing element, but also as the transmission medium for the detected signal. Since a large number of measured points share the same equipment, the cost of the equipment per measured point can be very low. In many practical cases, the cost of the distributed fiber-optic sensor is dominated by the cost of the fiber itself and the deployment of the sensor. As the price for optical fibers is reduced greatly due to the development of the technology, the cost mainly comes from the installation of the sensor system. The approach of distributed fiber-optic sensors provides an efficient way of simultaneously achieving multi-points sensing under a convenient and low-cost configuration.
