论文摘要
已经在77 K或较低的温度下测试了许多光学连接的关键活性和被动组件，这表明在液体氩时间投影室（LARTPC）检测器低温恒温器中运行的光学连接的潜在发展。在商业0.25-UM硅在赛车机上制造的环形振荡器，单个MOSFET和高速16：1的序列化器持续从室温到4.2 K，15 K和77 K的运作。三种类型的激光二极管从室温到77K。光纤和光学连接器显示出从室温到77 K的微小衰减变化。
A number of critical active and passive components of optical links have been tested at 77 K or lower temperatures, demonstrating potential development of optical links operating inside the liquid argon time projection chamber (LArTPC) detector cryostat. A ring oscillator, individual MOSFETs, and a high speed 16:1 serializer fabricated in a commercial 0.25-um silicon-on-sapphire CMOS technology continued to function from room temperature to 4.2 K, 15 K, and 77 K respectively. Three types of laser diodes lase from room temperature to 77 K. Optical fibers and optical connectors exhibited minute attenuation changes from room temperature to 77 K.
