The invention is an athermal waveguide device that helps counter the effects of parasitic, systematic, or environmental heat effects to improve optical device performance. The invention uses new combinations of materials that achieves the passive athermal performance of a silicon-based waveguide filter and also meets the very compact dimensions required by current Complementary Metal-Oxide-Semiconductor (CMOS) foundry standards. The device is both passive (meaning no power cost, making it less expensive) and scalable for mass manufacturing, making it a viable solution for the exponentially growing demand for heat management in optical systems, such as power management in data centers. Background: High temperatures can be detrimental to optical systems. Heat can hinder the performance, reliability, and lifespan of optical devices. To mitigate these effects and maintain optimal performance in optical systems, proper thermal management strategies are essential. Current solutions for this issue either compromise the compact design or may cost more by adding active thermal management controls in order to improve the performance of optical devices.
