“…[ 71 ] Compared with the single MRR which has a sharp resonance peak, the dual MRR is more suitable for high‐speed signals due to the flatter resonance peak. [ 85 ] The basic structure of the switch is shown in Figure a, which has 6 groups of dual MRRs forming a 4 × 4 reconfigurable optical switch network that is connected by waveguides and crossings. In each group, the basic switch element consists of two micro‐rings with the same resonance property, and it has two possible states of “bar” and “cross” states.…”

Recently, silicon‐integrated optical circuits have attracted intensive interests, thanks to the compatibility with the complementary metal‐oxide‐semiconductor (CMOS) technology that enables mass production at low cost. The optical switch is an essential part of optical integrated circuits, with broad applications in optical communications and networks, optical computing, and sensing such as LiDAR. In general, the silicon‐integrated optical switch adopts thermo‐optic or carrier dispersion effect to realize reconfigurable signal routing. However, the use of thermo‐optic effect leads to high power consumption, and the carrier dispersion effect has the disadvantage of small refractive index change. In addition, both effects are non‐latching, and hence, continuous power consumption is required even when switching is not needed. For overcoming these drawbacks, phase‐change materials (PCMs) have been introduced into silicon‐integrated optical switches. In this paper, silicon‐integrated optical switches are classified according to the underlying structure and recent research is reviewed. Recent studies on silicon‐integrated optical switches incorporating PCMs are also reviewed. Furthermore, the pros and cons of different types of integrated optical switches with and without PCMs are compared and discussed.

“…The high speed all optical networks required costeffective and energy-efficient technology for optical signal processing devices like optical add drop multiplexer (OADM), optical filters, all optical switches etc. Silicon photonics is well developed and many devices is fabricated using silicon on insulator (SOI) [1]. The ring resonators are cascaded to make all optical multiplexer and demultiplexer for DWDM systems.…”

In this paper we report on an eight-channel optical add drop multiplexer based on ring resonator using lithium niobate on insulator channel waveguides. It is suitable for a DWDM-GPON network with channel spacing of 100 GHz in C-band and data rate is 10 Gbps. The insertion loss at the drop port is maximum 1.2 dB and the Q-factor is 1636. It can be used as multiplexer as well as demultiplexer in 8-channel DWDM systems.
