Abstract

The invention discloses a silicon-based photoelectric integrated chip device and a transmitting system with the device, and the device comprises: an on-chip integrated electro-optical modulator whichis used for receiving an input light source and modulating an input electric modulation signal into an optical signal; an on-chip integrated optical filter which is used for filtering the modulated optical signal from the on-chip integrated electro-optical modulator and outputting the modulated and filtered optical signal; and at least one on-chip integrated optical coupler which is used for outputting the modulated and filtered optical signal. The on-chip integrated optical filter is adopted to roughly compensate the bandwidth of the transmitting system, and the on-chip integrated electro-optical modulator is adopted to finely compensate, so that the bandwidth compensation efficiency is improved, the signal-to-noise ratio is improved, the size of the device is reduced, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the field of semiconductor integrated circuit chips, in particular to a silicon-based optoelectronic integrated chip device and an emission system with the silicon-based optoelectronic integrated chip device. Background technique [0002] Silicon photonic integrated circuits (Si PICs) have gained tremendous attention due to the high-density integration capabilities of couplers, modulators, photodiodes, avalanche photodiodes, polarization diversity components, and multimode interferometers. With the increasing demand for bandwidth, the modulation rate of mainstream applications continues to increase, and the complexity of modulation formats gradually increases. However, the bandwidth of the optical transmission system is limited by the bandwidth of the modulator, the bandwidth of the driver, and the bandwidth of the package, and it is difficult to meet the increasing requirements of the modulation rate and modulation format. ...
