In the master's stage, I engaged in the research of fiber optic sensor.Optical fiber sensor is refers to the reflection of light by reading in the optical fiber transmission components change, of continuous distribution along the fiber information, such as temperature and deflection can be real-time correct detection of the sensor.I from the nature of the wavelength of light, realized the fun of science, and then began to study.A master degree after graduation, and I think to be engaged in academic research in different areas can promote the growth of its own, so the researchers chose to be the private sector of the road.

After entering the company, as an extension of the master's stage of research topic, I participated in the optical fiber sensor research and development, but for can predict the results of development always feel not satisfied.I want to belong to the unknown and new things for himself, just as I have this idea, the company assigned me to study of fiber itself.After the existing communication special optical fiber research and development of performance improvement, I now engaged in the research topic is the study of the multi-core optical fiber (MCF).

It is well known that optical fiber is transmitted light signal is a very fine line.Optical fiber, the spread of information to improve the speed and capacity of leap, it holds up to the height of the network as a representative, now the foundation of information society.But with video playback and smart phone all sorts of network services, such as the spread of the network data volume is increasing year by year.So far, people through a variety of innovative technologies for WDM does growing amount of data transmission, but the previous single mode fiber (SMF) transmission capacity is close to the limit.

SMF is known as the center of the nuclear cover after the formation of the shape of concentric circles with cladding, light locked within the nucleus of the only mode and transmission channel (light).Appeared to break the limit of SMF, increase the light in optical fiber channel "air separation reuse" research.Under the background of such studies, I focus on MCF and carry on research and development.Relative to the cladding in only one nuclear past optical fiber, MCF in a cladding with multiple cores, can expect there will be a leap to improve its transport capacity.But because of with multiple cores, it has the characteristics of SMF have no degradation, can solve the problem, is a big issue in the process of practical application.

Does WDM: multiple signals with different wavelengths of light transmission, increase each transmission technology of the optical fiber transmission capacity.

One of the problems, is the crosstalk between nuclear signal interference (XT), degrade the quality of the communication.I found by experiments is much greater than in the past theory to forecast the occurrence of XT, confirm and verify the phenomenon is caused by fiber bending of light waves between nuclear deviation, on this basis, according to the opposite, I developed a use due to the bending of light waves deviation method to suppress the XT, and in 2011, and information communication research institutions such as the global for the first time, with greater than SMF capacity limit 100 TB/s transmission capacity of transmission experiment, a success.As the latest achievements in the (strain) and KDDI comprehensive research institute, besides inhibition of XT, we also intranuclear mode, by increasing the die division multiplexing, to achieve more than SMF 100 times the maximum capacity of 100 TB/s (10 pb/s) of the large capacity transmission.

In addition to this, I and Bell Laboratories (now called Nokia Bell Labs) around allows the XT, were studied by the method of signal receiver for recovery.By allowing XT can make more close to the nucleus, with even with the same roughness, and the existing standard optical fiber can realize the advantages of large capacity, but the light of different channel leads to receive the signal delay, information recovery needs a large number of calculations, it has become a big issue.So I separate implementation can significantly inhibit signal delay MCF design, through trial production test, confirmed in more than 10000 km long distance transmission, it still has good practicability.In addition in the trial production, by the company is good at extremely low loss optical fiber manufacturing technology of the design, and manufacture technical personnel's efforts, has achieved the extremely low loss and high quality at the same time the SMF match low loss.

Through a standard 125 mu m optical fiber diameter, achieved in the aspect of the optical properties is also very good for the combination of long and large capacity transmission type multi-core optical fiber and the multi-core optical fiber both in terms of transmission performance, or in the mechanical reliability of glass fiber, cope with the future traffic increase, has good practicability, I think it is only in view of the practical project, the optical society of America prize will be awarded to me.This is my as a milestone in the history of the researchers in the study, now I am doing the work of research and practical production.

As a researcher, I always think, when encounter new things and issues until they understand and recognition, should be constantly validation and thinking in the conclusion, textbook content such as books and papers, whether there is any omission or negligence.

Research, is the encounter with the unknown and new things constantly, and explores the world.Sometimes face difficulties.In order to break through these obstacles, should be thoroughly thinking, and constantly explore the essence of things.This is my style as a researcher.I hope with this attitude, grow up to be a promotion of technology evolution, produces are widely used in the social technology and products of the researchers.
