“…[82,[107][108][109] In addition, whilst it can support relatively large operation bandwidth, it has limited wavelength selectivity. On the other hand, the MRR structure has advantages of compact footprint, wavelength selectivity, and relatively low power consumption, [60,[110][111][112] However, it also has the disadvantages of narrow bandwidth, temperature susceptibility, and requiring high processing accuracy. [113][114][115] This is in contrast with the typical demands for broad operation bandwidth and stable operation, such as allowing the use of multiple signal wavelengths to increase the overall capacity of data transfer, which is important to support the increasing volume of data that needs to be processed and interconnected.…”

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.
