Abstract:

A side joined diagonally arranged triple asymmetric optical ring resonator (TAORR) is modelled and analysed as optical add-drop filter (OADF). The delay line (DL) approach is used to model the structure whose transmittance is deliberated in Z-plane using Mason’s principle. The transmittance is observed from signal flow graph of the model. The performance is analysed in terms of Free-Spectral-Range (FSR), Dispersion (DP) and Group Delay (GD) in MATLAB environment. The field transmission is observed at ON resonance condition in finite-difference-time-domain (FDTD) method. The performance of TAORR is also investigated by presenting “EYE” diagram in Opti-System software. High FSR, low crosstalk and open eye diagram make TAORR model exceptional from other optical filters.

I. Introduction

The renowned name in the family of integrated optics is micro ring resonator (MRR). Its vast execution in the field of Optical-switch [1], modulation [2], sensing [3], signal processing [4], wavelength division multiplexing (WDM) [5], optical filtering etc. increase the research area over optical discipline. In the integrated photonic platform, it is a suitable component because of its high efficiency, low loss and small size. Particularly, the micro and nano-fabrication process of silicon photonic technology has opened a new era to the research world and it has revolutionized the optoelectronics and photonics industry by its countless advantages especially for complementary metal-oxide semiconductor (CMOS) [6]. In Fiber optic communication channel, the application of OPADF always depends on the large Bandwidth (BW). So our main aim is to increase the BW by increasing the FSR. The Fabry-Peot ring resonator structure where single ring was coupled with 2 bus waveguides (B-Ws) and double ring structure ware developed by Suzuki et al. [7]. The structure was capable to provide the FSR of l4.3GHz and 98 GHz respectively. In the next stage of research, Mandal.et al. [8] introduced three rings coupled with two B-Ws that provides the FSR of 200GHz. The FSR was further increased by S. Addya and S.B. Dey by modelling four MRRs coupled with two B-Ws [9]. The same approach was followed by F. Rukerandanga et al. [10] by modelling six MRRs based OADF. MRR based OADF by using silicon on insulator (SOI) material was projected by L. Tozzetti et al. [11]. The band-pass filter was designed by N.Kohli et al. [12] by serially joined MRRs. The add-drop optical filter is explained by H. J. Borkakati et al. [13] by using photonic crystal ring resonator.
