“…The other advantages of the ring resonator structure is that it can easily modified into another form to increase the performance. Some examples of the development of the structure of ring resonators are Single Microring Resonator (SMR) [4], Parallel Cascaded Microring Resonator (PCMR) [5], Serial Cascaded Microring Resonator (SCMR) [6], Multi coupled Ring Resonator (MCRR) [7] which have been investigated for communicaions and sensors aplications. The ring resonator structure also can be applied with vernier effect to achive high sensitivity levels of sensing [2], [8], [9].…”

In this paper, a multi-path optical ring resonator (MpORR) on silicon-on-insolator (SOI) is proposed for sensitivity enhancement in liquid chemical sensing applications. It is designed on Silicon Dioxide (SiO 2 ) substrate and Silicon material as the core of optical waveguides. The proposed multi-path optical ring resonator can be realized with a wide free spectral value (FSR) of 3 THz. Therefore, the sensitivity of the sensor can be enhanced. Analysis and optimization of the proposed multipath optical ring resonator are discussed and reported for optical wavelength operation of 1550 nm. The proposed device can be used for identifying different liquid material precisely.

Filter will be one of the most important components of the next generation of optical communications. Micro-ring resonators have been widely studied as a potential device for dense wavelength filter due to its advantages. In this paper, a waveguide-based microring-resonator type of interleave filter is investigated. The cascade structure is applied to obtain better characteristics of filter spectra. Our calculation shows that, compared with 2-stage or 4-stage cascade, 3-stage cascaded microring resonator has better performance with pass-band width of 22 GHz, ripple ratio < 1 dB, crosstalk of -33 dB for 1×2 interleaver and -24 dB for 1×4 interleaver. Numerical calculation also clearly shows that general optical waveguide types is reasonable as microring resonator with insertion loss < 2 dB

1 Abstract-Limited sensitivity and sensing range are arguably the greatest challenges in microwave sensor design. Recent attempts to improve these properties have relied on metamaterial-(MTM-) inspired open-loop resonators (OLRs) coupled to transmission lines (TLs). Although the strongly resonant properties of the OLR sensitively reflect small changes in the environment through a shift in its resonance frequency, the resulting sensitivities remain ultimately limited by the level of coupling between the OLR and the TL. This work introduces a novel solution to this problem that employs negative-refractiveindex TL (NRI-TL) MTMs to substantially improve this coupling so as to fully exploit its resonant properties. A MTM-infused planar microwave sensor is designed for operation at 2.5 GHz, and is shown to exhibit a significant improvement in sensitivity and linearity. A rigorous signal-flow analysis (SFA) of the sensor is proposed and shown to provide a fully analytical description of all salient features of both the conventional and MTM-infused sensors. Full-wave simulations confirm the analytical predictions, and all data demonstrate excellent agreement with measurements of a fabricated prototype. The proposed device is shown to be especially useful in the characterization of commonly-available high-permittivity liquids as well as in sensitively distinguishing concentrations of ethanol/methanol in water.
