Abstract: Coherent transceiver optical devices are the key devices of coherent optical communication systems. With the development of coherent optical communication systems towards larger capacity, longer transmission distance, and lower cost, coherent transceiver optical devices face a series of new requirements and challenges, including high bandwidth, wide spectral band, high performance, high reliability, high integration, and low power consumption.Future technology evolution of coherent transceiver optical devices includes: new material optical chips, advanced packaging technologies, and multi-channel integrated architectures. A variety of materials will exist in optical chips, including silicon photonics, indium phosphide and thin-film lithium niobate, as well as heterogeneous integration technologies based on silicon photonics platforms. The optical device will refer to the advanced packaging technology of the microelectronics industry to reduce the high-speed electrical signal transmission distance between chips, and ensure package reliability. The device-level multi-lane integration meets the needs of future multi-wavelength transmission architectures.
