Photonic Programmable Tele-Cloning Network

The concept of quantum teleportation allows an unknown quantum states to be broadcasted and processed in a distributed quantum network. The quantum information injected into the network can be diluted to distant multi-copies by quantum cloning and processed by arbitrary quantum logic gates which were programed in advance in the network quantum state. A quantum network combines simultaneously th...

Programmable photonic crystal nanobeam cavities.

We present dynamically reconfigurable photonic crystal nanobeam cavities, operating at ~1550 nm, that can be continuously and reversibly tuned over a 9.5 nm wavelength range. The devices are formed by two coupled nanobeam cavities, and the tuning is achieved by varying the lateral gap between the nanobeams. An electrostatic force, obtained by applying bias voltages directly to the nanobeams, is...

Chip-Scale Programmable Photonic Filters

Silicon photonic integrated circuits with electrically programmable non-volatile memory functions.

Conventional silicon photonic integrated circuits do not normally possess memory functions, which require on-chip power in order to maintain circuit states in tuned or field-configured switching routes. In this context, we present an electrically programmable add/drop microring resonator with a wavelength shift of 426 pm between the ON/OFF states. Electrical pulses are used to control the choic...

Using Photonic Integrated Circuits

Contention resolution and forwarding of labeled optical packets at 40 Gb/s is demonstrated utilizing multiple InP based optical buffers and monolithic wavelength converters. Layer-2 packet recovery measurements are presented. ©2009 Optical Society of America OCIS codes: (060.1810) Buffers, couplers, routers, switches, and multiplexers; (060.6719) Switching, packet
