Abstract
In the past years, significant progress has been made on the realization of high performance building blocks in photonic circuits, such as ultra-low loss waveguides, monolithic lasers, high-speed modulators, and high efficiency photodetectors. However, toward large scale integration with complete functions and breakthrough performance, there are still many challenging problems to solve. While silicon has proved to be an asset material for integrated optics, the combination of other materials with complementary properties has turned out to be critical for the realization of specific advanced photonic devices. Yet, the major challenge has been the materials’ differences that cause difficulties in hybrid integration. APL Photonics’ keen interest in the field leads us to offer this editorial, which will present a broad overview of the recent progress, current challenges, and future opportunities of hybrid photonics integration.
Highlights
Photonic devices have found wide applications covering but not limited to high-speed telecommunications, datacenters, sensing, photovoltaics, quantum information processing, and bio-photonics
Silicon photonics is booming and gradually accepted by industry, as it enables high yield and low cost integration by leveraging the standard complementary metal-oxide semiconductor (CMOS) manufacturing capabilities developed in microelectronics foundries
In the past two decades, silicon photonics has emerged as a mature technology, allowing for multiple optical functions to be integrated onto the same chip-based platform
