This paper reviews recent progress in integrated multiport optical switch, fabricated on silicon-on-insulator wafers. Typical topologies of multiport switch and the element switches are first described. Then, we review pioneering studies of the integrated multiport switches. We also describe feasible improvements, some of which will better fit the switch to a real use in telecommunication and some to enlarge the port count.

“…The lateral , transversal , and roll position of the FAS (1) are defined by three elastic pins (2) with respect to the solid world (3). The fiber array is mounted on a stacked, linear adjustable fiber-array mounting platform (5) located on top of the movable FAS (1). The fiber array can now be aligned on the axis to the input and output waveguides of the PIC (6), which is already mounted on the solid world (3).…”

“…3. The third linear z direction of the fiber array (4) to the PIC facet (6) can be controlled by a stacked platform (5) on top of the fiber array alignment submount FAS part (1). The position of the fiber array can be controlled by means of three removable pins (7), which are connected to three external piezoelectric actuators.…”

“…First, due to the high index contrast between InP-based waveguides and monomode fibers, mode matching is necessary to reduce losses in mode mismatch between single-mode fibers (8-m core diameter) and waveguides (typical dimensions 2 m 0.6 m). For simple fiber butt coupling, the losses are about 10 dB; therefore on-chip spot size converters (SSCs) are needed [1], [2]. Reviews of SSCs are given in [3], [4].…”

“…We consider that for small-and mid-scale switches, single-layer optical circuits are advantageous because of their simple designs, simple fabrication processes, and lowloss characteristics. Table I summarizes strictly nonblocking optical switch topologies applicable to single-layer optical circuits [9][10][11]. N is the number of input and output ports.…”

We propose and demonstrate a port-alternated switch-and-select architecture for planar waveguide-based optical switches. The proposed architecture reduces the number of intersections on a path, which leads to both small insertion loss and small path dependence. We demonstrate an 8 × 8 optical switch based on the proposed architecture using a silicon photonic platform, which exhibits a fiber-to-fiber insertion loss of 5.7 dB with a crosstalk below −30 dB. We discuss the scalability of the switch, including the propagation and bend losses of the waveguides.
