ABSTRACT Current optical interconnects are dominated by electrical wavelength converter module technologies which are not only power consuming but also bandwidth limited. We experimentally demonstrate a technique to maximize network robustness, flexibility and efficiency through combined adoption of energy-efficient VCSELs, distributed forward Raman, all-optical wavelength conversion and reuse. The precise wavelength selectivity of a fibre Bragg grating (FBG) is exploited to realize all-optical wavelength switch at 10 Gbps directly modulated 1549.60 nm VCSEL channel. The 6.2 dB flat gain of a forward Raman amplifier is exploited to achieve a 25.25 km downstream transmission of the switched channel incurring a 1.23 dB transmission penalty. Gain saturation of an Erbium-doped fibre amplifier (EDFA) is incorporated to achieve real-time all-optical data erase/rewrite. The 1549.62 nm VCSEL channel is further reused for upstream transmission of 8.5 Gbps data incurring a maximum penalty of 0.83 dB. Our concept is key for adoption in dynamic wavelength routing for spectral utilization in optical interconnect.

摘要 当前的光互连主要由电波长转换器模块技术主导，这些技术不仅耗电而且带宽受限。我们通过实验证明了一种通过结合采用节能 VCSEL、分布式前向拉曼、全光波长转换和重用来最大化网络稳健性、灵活性和效率的技术。利用光纤布拉格光栅 (FBG) 的精确波长选择性实现 10 Gbps 直接调制 1549.60 nm VCSEL 通道的全光波长切换。前向拉曼放大器的 6.2 dB 平坦增益用于实现交换信道的 25.25 公里下行传输，导致 1.23 dB 传输损失。掺铒光纤放大器 (EDFA) 的增益饱和用于实现实时全光数据擦除/重写。1549.62 nm VCSEL 通道进一步重新用于 8.5 Gbps 数据的上行传输，导致最大损失为 0.83 dB。我们的概念是采用动态波长路由以实现光互连光谱利用的关键。
