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.

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。这种特性使它们在分插滤波器和多路复用器应用中具有独特的功能。
