摘要	A monolithic optical transmitter photonic integrated circuit (TxPIC) comprises a plurality of integrated modulated sources which, when all operated at constant current, display a power output that varies as a function of array position similar to a quadratic-shaped curve and, further, forming an array of signal channels each having a different wavelength output. An optical combiner/decombiner is integrated in the circuit and has at least one free space region with a plurality of ordered bands along its edge where the zero order band is substantially at a longitudinal centerline of the free space region and where, on either side of this band, is a first order band followed by additional higher order bands. The ends of the output waveguides from the modulated sources are coupled approximate to the free space region edge along a region of the zero order band between one of the adjacent first order bands and a longitudinal centerline of the zero order band so that the inputs of the signal channels to the combiner of are titled or offset with respect to the longitudinal centerline of the combiner free space region so the combined outputs from the optical combiner will be aligned along the slope of the quadric-shaped curve of the combiner output passband envelope. The tilted combiner/decombiner may also be deployed in a receiver photonic integrated circuit (RxPIC) or other circuit employing such a device.
其他摘要	单片光发射器光子集成电路（TxPIC）包括多个集成调制源，当它们全部以恒定电流操作时，显示功率输出，该功率输出随阵列位置的变化而变化，类似于二次曲线，并且进一步形成信号通道阵列，每个信号通道具有不同的波长输出。光学组合器/分解器集成在电路中并具有至少一个自由空间区域，该自由空间区域沿其边缘具有多个有序带，其中零级带基本上位于自由空间区域的纵向中心线处，并且在其中的任一侧。这个频段是一级频段，其次是更高阶频段。来自调制源的输出波导的末端沿着相邻的一级波段之一和零级波段的纵向中心线之间的零级波段的区域近似于自由空间区域边缘耦合，使得输入波形的输入。到组合器的信号通道相对于组合器自由空间区域的纵向中心线标题或偏移，因此来自光组合器的组合输出将沿组合器输出通带包络的二次曲线的斜率对齐。倾斜组合器/分离器也可以部署在接收器光子集成电路（RxPIC）或采用这种器件的其他电路中。
