Not Accessible

Your library or personal account may give you access

Abstract

Thermal beam steering over 7° is realized on a slow-light waveguide amplifier with a narrow divergence angle below 0.3°. Measured data well agrees with theoretical calculations. Also we present electro-thermal beam steering by current injection.
