Abstract

We develop an energy efficient digital data link connecting cryogenic superconducting single flux quantum (SFQ) circuits to room-temperature electronics. The design is based on low-temperature (4 K) superconductor ERSFQ SFQ/dc drivers, high-temperature superconductor data cables spanning 4 K to 70 K temperature stages, mid-temperature (70 K) polarization modulation vertical cavity surface emitting lasers (PM VCSELs), and fiber optic links to room temperature electronics. The Energy-efficient Cryogenic Optical (ECO) data link design is based on balancing power dissipation and signal gain at each temperature stage to maximize overall energy efficiency following the recently introduced Thermo-Gain Rule. To achieve VCSEL light emission with two switchable distinct polarization modes, a cruciform-shaped anisotropic optical cavity is formed by fabrication of a photonic crystal with etched periodic air holes surrounding the unetched cruciform region. In this report, we present the results of design, fabrication, and preliminary testing of the ECO data link components.

节能低温光学(ECO)数据链的发展

我们开发了一种节能的数字数据链路，将低温超导单通量量子(SFQ)电路连接到室温电子器件。该设计基于低温(4 K)超导体ERSFQ SFQ/dc驱动器，跨越4 K至70 K温度阶段的高温超导数据电缆，中温(70 K)偏振调制垂直腔面发射激光器(PM VCSELs)，以及与室温电子设备连接的光纤链路。节能低温光学(ECO)数据链设计基于平衡每个温度阶段的功耗和信号增益，以最大限度地提高整体能源效率，遵循最近引入的热增益规则。为了实现具有两种可切换的不同偏振模式的VCSEL光发射，通过在未蚀刻的十字区域周围制造具有蚀刻周期性空气孔的光子晶体形成十字形各向异性光学腔。在本报告中，我们介绍了ECO数据链组件的设计、制造和初步测试结果。
