Slow Photon Light Activated Switch

Project description


FET Open cut-off 14/3/2006

SPLASH addresses the issues of optical switches, tunable delay lines and optical buffering that is essential for realising the vision of all-optical data processing. The consortium will realise these functions by exploring optical slow light structures based on coupled ring resonators and photonic crystal waveguides. The core demonstrators are,a) Broadband slow light. Photonic crystal waveguides that combine sizeable slowdown factors with broad bandwidth and efficient optical coupling. b) Tunable coupler. By exploiting slow light phenomena in photonic crystals, the coupler will be very compact (10's of µm), yet require only refractive index changes of order 10-3 for complete switching. Tuning will be thermo-optic, electro-optic and all-optical.c) Tunable delay line. Tunable ring resonators will be used to continuosly control the delay properties of a system of coupled resonators.d) Switchable optical storage. By tuning/detuning the elements of a coupled resonator delay line, optical information will be stored.Structures will be realised in silicon on insulator technology to achieve the maximum compactness and maximum number of bits stored/unit area.
