High performance optical transceivers for the industrial or military markets are rated to operate in harshenvironments (e.g., -40ºC 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 transceiversover this wide temperature range. This requires heating control of the device in order to operate it above theambient temperature. However, the excess heat generated within the module must be exhausted using thermallyefficient paths that are important to the control of the transceiver's temperature. However, these thermallyefficient paths act as a double-edged sword in cold environments, where the thermal transfer is reversed and themodule is cooled by the ambient through the efficient thermal path, causing a temperature control problem andtransceiver performance drift. This requires power-hungry electrically controllable thermal coolers whichReflex Photonics wishes to eliminate in order to reduce cost and power consumption of its modules.Accordingly, Reflex Photonics wants to investigate with this Engage project how microelectromechanicalsystems (MEMS) could be used to implement an array of actuators that can contact in different numbers withthe module. This will allow for the variation of the thermal conductivity of the thermal path dynamically andprovide a controllable thermal path that insolates the module in cold environments or can exhaust excess heat.To perform this investigation, Reflex Photonics wants to establish a new collaboration with Prof. FredericNabki at ETS. Prof. Nabki has extensive experience in the design and fabrication of MEMS devices and theirintegration in heterogeneous systems. This will provide a viability analysis of this novel concept that can thenbe implemented in Reflex Photonics' next generation transceiver modules, strengthening its market position.The concept resulting from this project will enable the implementation of a dynamically controlled thermalpath surface that can have application in a wide range of applications touching microelectronics as well. TheHQP trained in this project will be two PhD students and one research professional.

用于工业或军事市场的高性能光收发器被评定为在恶劣环境中工作（例如，-40播放C至85°C）。Reflex Photonics设计并生产这种收发器模块。这些模块旨在包括强大的热控制，以确保在此宽温度范围内的稳定性。这就需要对设备进行加热控制，以便在高于环境温度的情况下运行。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，这对收发器的温度控制很重要。然而，这些热高效路径在寒冷环境中充当双刃剑，其中热传递被逆转，并且湿气通过高效热路径被环境冷却，从而导致温度控制问题和收发器性能漂移。这就需要耗电的电控热冷却器，反射光子希望消除，以降低成本和功耗的模块。因此，反射光子希望调查与此Engage项目如何微机电系统（MEMS）可以用来实现一个阵列的致动器，可以在不同的数量与模块接触。这将允许动态地改变热路径的热导率，并提供一个可控的热路径，使模块在寒冷的环境中隔离或排出多余的热量。为了进行这项研究，反射光子学希望与ETS的FredericNabki教授建立新的合作关系。Nabki教授在MEMS器件的设计和制造以及异构系统集成方面拥有丰富的经验。这将提供一个可行性分析的新概念，然后可以在反射光子学的下一代收发器模块实施，加强其市场地位。该项目产生的概念将实现一个动态控制的热路径表面，可以在广泛的应用触摸微电子以及应用。在这个项目中培训的HQP将是两名博士生和一名研究专业人员。
