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.

工业或军事市场的高性能发电器被评估为在Harmhenvorments（例如-40ºC至85°C）中运营。反射光子学设计并将此类收发器产生为模块。这些模块旨在包括稳健的热控制，以确保收发范围的稳定性在此较宽的温度范围内。这需要对设备的加热控制，以便将其运行以上的温度。但是，必须使用对控制收发器温度很重要的热效率路径来耗尽模块中产生的多余热量。但是，这些热效率路径在寒冷环境中充当双刃剑，在该环境中，热传递逆转并通过有效的热路径通过环境冷却模块，从而导致温度控制问题和转移器性能钻孔。这需要渴望消除的电力控制的热冷却器，以降低其模块的成本和功耗，以减少其模块的成本和动力消耗。反射光子学希望通过此工程项目调查微电机械系统（MEMS）如何使用该项目来实现与模块数量不同的行动者的阵列。这将使热路径的热导率的变化动态并提供受控的热路径，该路径可损害模块在冷环境中或可以耗尽过多的热量。要执行这项投资，Reflex Photonics希望与ETS教授建立新的合作。 Nabki教授在MEMS设备的设计和制造及其在异质系统中的集成方面具有丰富的经验。这将提供对这一新颖概念的生存力分析，然后可以在Reflex Photonics的下一代收发器模块中实施，从而加强了其市场位置。该项目产生的概念将使可以在触摸微电灯的广泛应用中实现动态控制的热道path表面。在该项目中培训的TheHQP将是两名博士生和一名研究专业人员。
