Description
Technical Field
The invention belongs to the technical field of optical fiber communication, and particularly relates to an ultra-wideband tunable optical frequency comb generation device and method based on heterogeneous multi-core optical fibers.
Background
Today's internet transmits hundreds of trillions (10-10) per second 14 ) Bit data, which consumes 9% of the world's total power, continues to grow at a rate of 20-30% per year. Although a large number of optical fiber communication systems based on common single-mode single-core optical fibers and Wavelength Division Multiplexing (WDM) technology have been laid worldwide, the current optical transmission capacity has approached the bottleneck due to factors such as optical fiber nonlinearity. To further increase the transmission capacity, multidimensional multiplexing techniques (such as ultra-wideband wavelength division, spatial division multiplexing, etc.) are beginning to be adopted. Ultra-wideband multiplexing requires the use of a large number of high quality lasers of different wavelengths as the transmit laserA light source. However, the increase of the number of lasers will cause the system power consumption to increase, limiting further increase of the capacity of the optical communication system. Therefore, an optical frequency comb generation technology capable of realizing wide output bandwidth and tunable carrier spacing is urgently needed to support the technical support provided by the future ultra-large-capacity optical fiber communication system.
At present, a frequency-locked multi-carrier light source, i.e. an optical frequency comb, generated based on a single seed laser source is a key device for realizing a large-capacity optical fiber communication system. Recently, the electro-optical modulation optical frequency comb generation technology based on fiber nonlinearity has been widely researched due to the flexible and adjustable carrier frequency interval and wide bandwidth. But the structure is complex and not easy to integrate. How to simply and effectively realize the generation of the broadband tunable optical frequency comb is a key and difficult problem to be solved.
