由于其紧凑的尺寸，环形谐振器可以是用于许多密集波分复用（DWDM）组件以及许多低成本应用（诸如光学传感器电路的一部分或低成本光学信号处理）的具有成本效益的解决方案。调制器、滤波器、分插复用器和开关都是可以用环形谐振器实现的组件。它们潜在的较大自由光谱范围（FSR）、精细度和品质因子，以及低成本制造的潜力，使它们成为许多当前DWDM设备的可行替代方案。然而，对于商业上可行的这种设备，它们需要对输入信号的偏振状态不敏感。本文获得的结果表明，已经制造了单个输入/输出光学跑道谐振器，使得谐振光谱中的最小值对准到优于1 μ m。环还表现出相对较低的损耗，测量的Q因子约为90，000，精细度值为12。
Because of their compact size, ring resonators can be a cost effective solution for many Dense Wavelength Division Multiplexing (DWDM) components, as well as many low cost applications such as part of optical sensor circuits, or low cost optical signal processing. Modulators, filters, add-drop multiplexers, and switches are all components that can be realised with a ring resonator. Their potentially large Free Spectral Range (FSR), finesse, and quality factor, together with the potential for low cost fabrication, make them a viable alternative to many current DWDM devices. However, for such devices to be commercially viable, they need to be insensitive to the polarisation state of the input signal. The results obtained herein show that a single input/output optical racetrack resonator has been fabricated so that the minima in the resonance spectra align to better than 1pm. The rings also exhibit relatively low loss with measured Q-factors of approximately 90,000 and finesse values of 12.
