We present a Mach-Zehnder interferometer assisted ring resonator configuration (MARC) to realize resonator transmission spectra with unique spectral signatures and significantly large effective free spectral ranges. Transmission spectra with unique spectral signatures are generated by changing the angular separation between the through port and the drop port waveguides of the ring resonator (RR). These spectral signatures are comprised of several distinct resonance lineshapes including Lorentzian, inverse Lorentzian and asymmetric Fano-like shapes. One of the spectral signatures generated from the MARC device is utilized for the temperature sensing measurement to demonstrate a MARC-based sensor with high Q-factor and wide measurement range.
我们提出了一种马赫-曾德尔干涉仪辅助环形谐振器配置(MARC),以实现具有独特光谱特征和显著大有效自由光谱范围的谐振器传输光谱。通过改变环形谐振器(RR)直通端口和下路端口波导之间的角间距来生成具有独特光谱特征的传输光谱。这些光谱特征由几种不同的共振线形组成,包括洛伦兹线形、反洛伦兹线形和不对称类法诺线形。利用MARC器件产生的一种光谱特征进行温度传感测量,以展示一种具有高Q因子和宽测量范围的基于MARC的传感器。
