On-chip photonics devices relying on the weak, volatile thermo-optic or electro-optic effects of silicon usually suffer from high insertion loss (IL) and a low refractive index coefficient. In
The optical characteristics and coupling behavior with phase transitions have been numerically examined. With a compact coupling length of
In this paper, we propose and demonstrate a 32 × 4 optical switch using high-index doped silica glass (HDSG) for ROADM applications.

An 8×8 double-layer network (DLN) switch prototype is demonstrated with crosstalk of below −40 dB, on-chip loss of as low as 8.5 dB, and switching times of under 100 ns.
Large-scale photonic switches are essential components for telecommunications and interconnects, incorporating many cascaded 2 × 2 optical switches. To keep the excess loss of the entire switch
With losses this low it is difficult to reliably measure the loss with connectors, as connector loss can vary by 0.1 - 0.25 dB. Luminos CORALIGN™ Positioners
In this paper, we propose and demonstrate a 32 × 4 optical switch using high-index doped silica glass (HDSG) for ROADM applications.
