Investigation of a surface comprised of an array of micro-electro-mechanical actuators for the dynamic control of a thermal path

用于工业和军事市场的高性能光收发器被评定为在恶劣的 ** 环境（例如，-40 ° C至85°C）。Reflex Photonics设计并生产此类收发器模块。**这些模块旨在包括强大的热控制，以确保收发器 ** 在此宽温度范围内的稳定性。这需要对设备进行加热控制，以便在高于 ** 环境温度的温度下工作。然而，模块内产生的多余热量必须使用热效率高的路径排出，这对控制收发器的温度很重要。在寒冷的环境中，** 热传递是反向的，模块通过有效的热路径被环境冷却，导致 ** 温度控制问题和收发器性能漂移。这个问题需要耗电量大的 ** 电控热冷却器，Reflex Photonics希望消除这种冷却器，以降低其模块的成本和 ** 功耗。因此，Reflex Photonics希望继续与Nabki教授合作，研究如何使用 ** 微机电系统（MEMS）来实现可以与模块接触 ** 不同数量的致动器阵列。这将允许动态地改变热路径的导热性，并提供可控的热路径，该热路径将模块隔离在寒冷的环境中或可以排出多余的热量。与Nabki教授的合作将继续集中在设计 ** 设备上，这些设备源于前一个项目提出的两个概念：传输单元和隔离平台。这些器件可以成为Reflex Photonics下一代收发器 ** 模块热控制的基础，从而巩固其市场地位。该项目产生的器件将实现动态控制的热路径 ** 表面，该表面也可以应用于接触微电子的广泛应用中。本项目培训的HQP** 将包括一名博士生、一名硕士生和两名研究专业人员。

High performance optical transceivers for industrial and military markets are rated to operate in harsh**environments (e.g., -40°C to 85°C). Reflex Photonics designs and produces such transceivers into modules.**These modules are meant to include robust thermal control in order to ensure the stability of the transceivers**over this wide temperature range. This requires heating control of the device in order to operate above the**ambient temperature. However, the excess heat generated within the module must be exhausted using thermally**efficient paths that are important to the control of the transceiver's temperature. In cold environments, the**thermal transfer is reversed and the module is cooled by the ambient through the efficient thermal path, causing**a temperature control problem and transceiver performance drift. This problem requires power-hungry**electrically controllable thermal coolers which Reflex Photonics wishes to eliminate in order to reduce cost and**power consumption of its modules.**Accordingly, Reflex Photonics wants to continue its collaboration with Prof. Nabki to investigate how**microelectromechanical systems (MEMS) could be used to implement an array of actuators that can contact in**different numbers with the module. This will allow for the variation of the thermal conductivity of the thermal**path dynamically and provide a controllable thermal path that insolates the module in cold environments or can**exhaust excess heat. The continuation of this collaboration with Prof. Nabki will be focused on the design of**devices stemming from two concepts proposed after the prior project: a transfer cell and an isolation platform.**These devices can then be the basis for thermal control of Reflex Photonics' next generation transceiver**modules, strengthening its market position.**The devices resulting from this project will enable the implementation of a dynamically controlled thermal path**surface that can have application in a wide range of applications touching microelectronics as well. The HQP**trained in this project will be one PhD student, one Master student and two research professionals.
