Ultra-compact packaged optical/electrical conversion array module

针对传统微波光子产品通道数多、体积和功耗大、集成度低的问题,设计了一种基于微波光子混合集成封装技术的超紧凑封装光/电转换阵列模块,通过将光子器件、微波芯片、可调衰减芯片、电路系统封装入一个壳体内,可以在超紧凑空间内实现光/电转换、信号放大、衰减可调和均衡等多项功能。测试结果表明:该模块在2~18 GHz频段光电响应度较高,大于0.8 A/W;6个通道的S21的平均值为-3.5 dB,每个通道的平坦度在±1.5 dB以内,通道隔离度大于55 dB,且驻波反射小于1.7。

Aiming at the problems of large number of channels,large volume and power consumption and low integration of traditional microwave photonic products,an ultra-compact package optical/electrical conversion array module based on microwave photonic hybrid integrated packaging technology is designed.The photonic device,microwave chip,adjustable attenuation chip and circuit system are sealed into a shell.It can realize many functions such as optical/electrical conversion,signal amplification,attenuation adjustable and equalization in ultra-compact space.The test results show that the photoelectric responsiveness of the module is higher than 0.8 A/W in the 2~18 GHz band.The mean value of S21 for the six channels is-3.5 dB,the flatness of each channel is within±1.5 dB,the channel isolation is greater than 55 dB,and the standing wave reflection is less than 1.7 dB.
