Design Methods for Optical Couplers

Home / Design Methods for Optical Couplers

In this review article, we survey three major light coupling methods between optical fibers and integrated waveguides: end-fire coupling, diffraction grating-based coupling, and adiabatic coupling. Optical interconnects is an important issue in silicon photonic integrated circuits for transmitting light, and fiber-to-chip optical interconnects is vital in application scenarios such as data centers and optical transmission systems. As datacenters strive to meet escalating demands for efficiency and bandwidth, particularly with the integration of AI and ML technologies, optics is poised to play a crucial role in shaping the future of interconnect architecture and performance. Led by senior application engineers and a guest speaker from MIT, this webinar will equip you with the.
