Here, we're pioneering a novel approach in photonics, targeting the development of ultra-low power communication systems and advanced sensing technologies. Central to our strategy is the implementation of a unique zig-zag structure, designed to achieve femtojoule (fJ) per bit communication efficiency. A key innovation in our approach is the integration of unidirectional coupling through on-chip isolation, seamlessly connecting a Transverse Coupled Cavity VCSEL (TCCVCSEL) to the modulator and then to a waveguide. This project has wide-ranging implications, extending beyond just creating new devices. It's geared towards establishing a robust III/V platform, serving as a cornerstone in the field of photonics and integrated circuit technology. Our work is poised to catalyze advancements in high-speed, low-power photonic systems, potentially setting new benchmarks in the industry.
