Proposal of 1 × 8 and 8 × 1 All-Optical Controllable Switch Arrays by Dipole Induced Transparency Applicable in DWDM

Controllable motion of optical vortex arrays using electromagnetically induced transparency.

We demonstrate control of the collective motion of an optical vortex array using an electromagnetically induced transparency media. Scanning the frequency detuning between the pump and probe fields changes the susceptibility of the media, producing a unique effective diffraction of the vortex array for each detuning. We measure several experimental configurations and compare them to numerical s...

Editorial, Volume 8, Issue 1

A new vocabulary item has been added to English dictionaries: Covid-19. For linguists, the addition of a meaningful linguistic element to any language should change the whole language as, for T. S. Eliot, a new poem changes the whole literature of a nation. But let us see how seriously the addition of the vocabulary item Covid-19 might change the English language. According to Cambridge online ...

Integrated Optical Buffer Using InP 1×8 Switch and Silica-Based Delay Line Circuit

We demonstrate a compact optical buffer module, comprising an InP 1×8 phased-array switch and a silica-based delay line circuit. Tunable and uniform buffering of up to 21 ns is obtained with a 3-ns temporal resolution. ©2012 Optical Society of America OCIS codes: (130.3120) Integrated optics devices; (130.4815) Optical switching devices; (060.1810) Buffers, couplers, routers, switches, and mult...
