随着对高速、超紧凑数据信号管理需求的日益增长,光子集成电路(Photonics Integrated Circuits,PIC)在先进的光子信号处理中受到广泛关注,其中可编程光芯片因其特有的通用性、可重构特性逐渐受到开发者的青睐.本文依托联合微电子中心有限责任公司(United MicroElectronics Center Co. Ltd,CUMEC)的绝缘体上硅(Silicon-On-Insulator,SOI)自主工艺平台,设计并制备了包含9个六边形单元的3×3六边形架构可编程光芯片,利用迭代扫描法实现了消光比高达30 dB的开关电压标定,并通过扁平化版图优化设计使芯片尺寸降低了21%;采用此可编程光芯片进一步完成了典型功能验证:通过对输入输出端的可调基本单元(Tunable Basic Unit,TBU)耦合系数进行调谐,可实现消光比、谐振波长、自由光谱范围可调的马赫曾德尔干涉仪(Mach-Zehnder Interferometer,MZI)/ 微环谐振腔(Micro-Ring Resonator,MRR),消光比可高达42.3 dB/28 dB;可实现延时量大范围可调谐的延时线及任意输入/输出端口之间的路由.该芯片是目前世界上规模最大的六边形架构可编程光芯片,并实现了与有源单元的单片集成,在微波光子信号处理、化学生物传感、量子信息、光计算领域具有广阔的应用前景.
With the increasing demand for high-speed
ultra-compact data signal management
photonics integrated circuits (PIC) have attracted extensive attention in advanced photonic signal processing. Programmable photonic chips are gradually becoming favored by developers for their inherent generic and reconfigurable features. Based on United Microelectronics Center Co.
Ltd (CUMEC) silicon-on-insulator (SOI) integrated photonics platform
we have designed and fabricated a 3×3 hexagon-shape programmable photonic chip containing 9 hexagon units. The optical switch's extinction ratio of up to 30 dB was achieved by the “Iteration Scanning Method”
and there is a 21% chip size reduction through “Flatting” layout optimization. The typical functions of this programmable chip are further verified by tuning the input/output coupling coefficients of tunable basic unit (TBU). This allows for a Mach-Zehnder interferometer (MZI) or a micro-ring resonator (ORR) with a tunable extinction ratio
resonance wavelength and free spectra range to be realized
and the corresponding extinction ratio can reach 42.3 dB and 28 dB
respectively. Other functions
such as an optical delay line with a wide tunable range
as well as routing between any input and output ports
are also successfully realized with this programmable photonic chip. This is the largest scale hexagon-shape programmable chip which could be integrated with active devices. This chip offers a wide range of potential applications
in the areas of microwave photonics signal processing
bio-chemical sensing
quantum information and optical computing.
