对不同氧化孔径尺寸的高速, 低能耗的垂直腔面发射激光器(VCSEL)进行了相对强度噪声(RIN)分析.小氧化物尺寸孔径的VCSELs器件更适用于低能耗数据传输, 且RIN特性与低能耗性能没有冲突.实验结果表明, 适合低能耗、高温度稳定性工作的小氧化孔径VCSELs器件同时表现出较好的噪声性能.高速低能耗VCSEL能够满足32GFC光纤通道标准的RIN要求, 在将来的高性能计算机应用中具有巨大优势.

Oxide-aperature-diameter dependent analysis of RIN for high-speed, energy-efficient Vertical-Cavity Surface Emitting Lasers (VCSELs) have been performed. Small oxide-aperture diameter VCSELs are prefered for low energy consumption data transmission. We demonstrate that energy efficiency is not in conflict with our VCSELs′ RIN characteristics. The experimental results indicate that small oxide-aperture diameter VCSELs, which are the most suitable for energy-efficient, temperature-stable operation, exhibit lower laser RIN due to less mode competition inside the smaller optical cavity volume. Our energy-efficient VCSELs fulfill the RIN requirements of the 32G Fibre Channel standard. These devices are advantageous for future high performance computer applications.
