Not Accessible

Your library or personal account may give you access

Abstract

A 16 element corrugated waveguide array fabricated in a single step is demonstrated to achieve over 15° of steering via wavelength tuning. Optical crosstalk suppression is achieved by inserting 2D photonic crystal between array elements.
