Abstract

The invention discloses a wavelength division multiplexing and demultiplexing optical structure, which comprises a transmitting end optical structure and a receiving end optical structure, wherein the transmitting end optical structure comprises a wavelength division multiplexing device and a first collimator, and the receiving end optical structure comprises a second collimator and a wavelength division demultiplexing device. The wavelength division multiplexing and demultiplexing optical structure is characterized in that the wavelength division multiplexing device and the wavelength division demultiplexing device are combined to a whole body including a glass block, a transmitting end band-pass filter group and a receiving end band-pass filter group, the transmitting end band-pass filter group is arranged on the lower half part of the glass block, and the wavelength division multiplexing device is formed by the transmitting end band-pass filter group and the lower half part of the glass block; the receiving end band-pass filter group is arranged on the upper half part of the glass block, and the wavelength division demultiplexing device is formed by the receiving end band-pass filter group and the upper half part of the glass block; the receiving end optical structure further comprises a rhombic prism capable of turning a light beam emitted by the second collimator to the wavelength division demultiplexing device. According to the wavelength division multiplexing and demultiplexing optical structure, by adopting micro-optics principle design, the insertion loss of the light beam can be greatly reduced, and the coupling efficiency is improved.

Description

technical field [0001] The invention relates to an optical transceiver module in optical fiber communication technology, in particular to an optical structure for wavelength division multiplexing and demultiplexing in a high-speed transceiver system. Background technique [0002] With the increasing development of the communication field, traditional transmission technologies have been difficult to meet the requirements of transmission capacity and speed. In typical application fields such as data centers, network connections, search engines, high-performance computing, etc. Carriers and service providers have deployed a new generation of high-speed network protocols, which require corresponding high-speed transceiver modules to meet high-density and high-speed data transmission requirements. In the high-speed information transceiver system, it is necessary to replace the traditional optical module with a high-density optical module. Using multi-channel optical transcei...
