Paper Abstract

We discuss that hybrid concepts are fundamentally more suited to meet simultaneously the goal of low optical and electrical switching energies and high speed operation. Recently, we have developped an optical threshold switch with gain which can be monolitically integrated and which is suitable for frequencies up into the GHz range and has a gain-bandwidth product of up to 30 GHz. By combining this switch with n-i-p-i or hetero n-i-p-i based electro-optical modulators to form "smart pixels" we obtain optical gates which fulfill all the requirements for applications in optical processors such as low optical and electrical switching energy, high speed, high fan-out, and large tolerances in signal energy.
