提出了仅使用C波段光模块和全光波长转换(AOWCs)的三波段(S+C+L)传输系统,不使用S波段和L波段光模块。虽然AOWC采用了高度非线性的光纤,但它不适用于光子集成电路(PICs)。对于波长转换成功的器件,富氮化硅(SRN)波导提供了卓越的性能,因为它适用于PIC,并且比传统的化学计量氮化硅波导具有更高的Kerr非线性。因此,在本研究中,我们提出了一种全光同步波长转换方法,该方法可以经济有效地在基于SRN波导中四波混频的PIC上制造。介绍了一种用于宽带AOWC的SRN波导的设计,并演示了64通道64 gb /s QPSK信号在C+L波段和s波段之间的双级AOWC的成功工作,这对宽带传输系统是有用的。
The triple-band (S+C+L) transmission system using only C-band transceivers and all-optical wavelength conversions (AOWCs) without S- and L-band optical transceivers have been proposed. Although an AOWC employs highly nonlinear fibers, it is not applicable to photonic integrated circuits (PICs). For a device with successful wavelength conversion, a silicon-rich nitride (SRN) waveguide provides superior performance, as it is applicable to PIC and facilitates a higher Kerr nonlinearity than conventional stoichiometric silicon nitride waveguides. Thus, in this study, we propose an all-optical simultaneous wavelength conversion method that can be cost-effectively fabricated on a PIC based on four-wave mixing in SRN waveguides. Following an explanation regarding the design of an SRN waveguide for wideband AOWC, the successful operation of a double-stage AOWC of 64-channel 64-Gb/s QPSK signals between the C+L bands and the S-band is demonstrated, which is useful for wideband transmission systems.
