Problems solved by technology

[0006] Existing optical receivers are large in size and high in production cost, which is not conducive to large-scale integration
The loss of the optical signal through multiple transmissions such as reflection and transmission is not considerable, and the production tolerance is relatively high, which is tantamount to greatly increasing the production cost

Abstract

The invention discloses a polarization-independent silicon-based optical wavelength division multiplexing receiver and device for 5G communication. The receiver comprises a two-dimensional grating coupler for receiving optical signals, an optical cross connector, two multimode interference couplers, a bidirectional angle multimode interference coupler optical wavelength division multiplexing device and a germanium waveguide detector. According to the receiver, sensitivity to the polarization state of the optical signal is effectively improved, optical loss can be reduced, and the bit error rate is reduced.

Description

technical field [0001] The invention relates to silicon-based optoelectronic technology, in particular to a polarization-independent silicon-based optical wavelength division multiplexing receiver and device for 5G communication. Background technique [0002] With the advent of the 5G Internet era, various new network applications such as big data, cloud computing, and artificial intelligence have gradually entered people's lives, and data communication traffic has exploded. Cost and other requirements are getting higher and higher. The traditional electrical interconnection, due to its insurmountable "electronic interconnection bottleneck", limits the further improvement of network speed and bandwidth, and has been unable to meet the current network's large bandwidth and high speed requirements. The information exchange mode based on optical interconnection technology can overcome the speed and bandwidth limitations of traditional electrical interconnection networks with i...
