Group delay and quadratic dispersion in optical microring resonator filters

由波导、谐振器、半导体放大器、多路复用器等组成的微米级光子电路，是现代通信、仪器和医学中使用的设备的基本组成部分。我的工作涉及开发这些电路的一个子集，其主要组成部分是环形或圆盘谐振器，由单片表面波或掩埋异质结构技术制造。与支持反向传播波的驻波（轴向模式）法布里-珀罗谐振器相反，微环和微盘是单向行波器件，只有在故意发射或由嵌入的不连续性创建时才会发生相反方向的同时传播。这个属性引起了他们的独特功能，在添加/删除过滤器和multiplexerapplication.Within的框架内，这个资助申请，我将完成我的工作的第二个和最后阶段的多环光学复用器的设计与扩展的自由光谱范围（FSR），特别强调的限制所施加的波导，散射和辐射损耗。我也将继续我的工作，与耦合微环建立复合反射器，以调查他们的一些特点，控制他们的使用作为激光反射镜和干涉仪。最后，我计划继续我的工作，分析群延迟和多环滤波器设备的色散，以有助于“色散或相位工程”的新艺术。

Micrometer size photonic circuits composed of waveguides, resonators, semiconductor amplifiers, multiplexers, etc., is the fundamental constituent of the devices used in modern communication, instrumentation and medicine. My work relates to the exploitation of a subset of these circuits whose main component is the ring or disk resonator, fabricated by monolithic surface wave or by buried hetero-structure technology. In contrast to standing wave (axial mode) Fabry-Pérot resonators supporting counterpropagating waves, microrings and microdisks are unidirectional traveling wave devices, where simultaneous propagation in opposite directions occurs only if deliberately launched or created by an embedded discontinuity. This property gives rise to their unique features in add/drop filter and multiplexer applications.Within the framework of this grant application I shall complete the second and final phase of my work on the design of multiring optical multiplexers with extended free spectral range (FSR), with special emphasis on limitations imposed by waveguide, scattering and radiation loss. I shall also continue my work on composite reflectors built with coupled microrings to investigate some of their characteristics that control their use as laser mirrors and in interferometers. Finally, I plan to continue my work analyzing the group delay and dispersion of multiring filter devices to contribute to the novel art of "dispersion or phase engineering".
