Abstract

The embodiment of the present invention provides an optical receiving and transmitting integrated machine used in an optical access system or an optical interconnection system, which can complete the function of receiving or reflecting an optical signal, or simultaneously complete the function of receiving and reflecting a signal in a certain proportion function, the device can also perform optical amplitude modulation and optical phase modulation of local signals, and support high-order optical modulation formats. Optical port and optical receiver. The realization of these functions depends only on the difference of the loading voltage on the device, so it is easy to control, and the function of the device can be tuned according to the needs. The device is easy to be integrated on a silicon-based optical chip, so it is easy to form a low-cost and high-reliability optical module, which is applied in optical communication and optical interconnection systems.

Description

technical field [0001] The invention relates to an optical signal transceiving device composed of integrated optical devices, in particular to an integrated optical signal transceiving device applied to optical access and optical interconnection. Background technique [0002] Integrated photonic devices are a key technology in the field of optoelectronics. Due to the development of technology, people have been able to produce passive optical devices such as optical couplers, optical beam splitters, and optical filters, or active optical devices such as optical modulators and electro-optic switches on optical chips made of silicon-based materials. Since silicon-based integrated devices using silicon-on-insulator (Silicon-On-Insulator, SOI) technology are well compatible with CMOS processes, silicon-based devices are easy to mass-produce and have cost advantages. The optical interconnection equipment, optical communication and optical network devices are integrated on a singl...
