It is a great honor for us to present this special topic on
optoelectronic technology and its applications in SCIENCE
CHINA. Information optoelectronics is widely used in
optical communications, computing, sensing, and military
applications. Currently, communication networks are facing
capacity and power consumption challenges due to the
ever-increasing requirements of users. Optoelectronic
technologies are the effective solution to break the electronic
bottleneck and improve the network performance, resulting
in booming of novel optoelectronic devices.
There are three main development trends for
optoelectronics. Multiplexing technologies are developing towards
multiple dimensions, such as wavelength-division
multiplexing (WDM), orthogonal frequency division
multiplexing (OFDM), polarization-division multiplexing (PDM),
and space-division multiplexing (SDM). The optoelectronic
devices are progressing from discrete components towards
high density integration chips, and on-chip integration
facilitates the development of novel information transmission
and processing architectures. The combination of the optical
and microwave technologies is another trend for
optoelectronics advancement, and microwave photonic techniques,
devices, and systems enable the generation, transmission,
detection, processing, and control of microwave signals in
optical domain.
The purpose of this special issue is to document recent
developments and trends in the field from both experimental
and theoretical perspectives. This topic contains 16 papers
selected from the major research groups in this field in
China. We would like to thank all the authors for their
excellent contributions and original ideas. We are grateful to
our reviewers who have provided thorough evaluations of
the submitted manuscripts.
