Dynamically reconfigurable optical packet switch (DROPS)

Dynamically reconfigurable optical packet switch (DROPS).

A novel Dynamically Reconfigurable Optical Packet Switch (DROPS) that combines both spectral and spatial switching capabilities is proposed and experimentally demonstrated for the first time. Compared with an Arrayed Waveguide Grating Router (AWGR), the added spatial switching capability provided by the microelectromechanical systems (MEMS) enables dynamically reconfigurable routing that is not...

Hardware Context-Switch Methodology for Dynamically Partially Reconfigurable Systems

Nowadays, the hardware of field programmable gate arrays (FPGAs) can be reconfigured both dynamically and partially. A dynamically and partially reconfigurable system can share hardware contexts among various hardware tasks. However, such FPGA systems require much memory to save the hardware context. To solve this problem, this work proposes a methodology for switching hardware context in dynam...

Reconfigurable 1×4 InP-based optical switch

An integrated 1 4 InP-based optical switch is reported. The device is quite simple and full device operation is achieved by injecting electrical currents to two electrodes. Since the operation of the switch relies on current spreading, using the carrier-induced refractive index change in InGaAsP multiple quantum wells, an area-selective zinc in-diffusion process is used to regulate the current ...
